Caio Bonfim is set to defend his title at the third leg of the World Athletics Race Walking Tour Gold series &ndash; the Korzeniowski Warsaw Race Walking Cup &ndash; on Sunday (5) but the Brazilian faces an intriguing challenge from Toshikazu Yamanishi.
The two-time world champion from Japan was at the peak of his game following Olympic bronze, a second world title in 2022 and the World Race Walking Team Championships individual victory in Muscat. Then came 2023, and a somewhat rockier road.
A telling result almost exactly a year ago to the day was third place at the Rio Maior Gold Tour race when Yamanishi, who has a 1:17:15 personal best, had no answer to a last 5km as Bonfim and Ecuador&rsquo;s Brian Pintado disappeared into the distance. Yamanishi finished in 1:20:58, more than a minute behind second-place Bonfim.
His 24th position at the World Championships in Budapest was nearly a minute slower still. And that rarest of things, a disqualification, was his unwelcome 28th birthday present at the Japanese Race Walking Championships in Kobe in February.
However, Yamanishi is looking not just to this race, or the Olympics in Paris, but to the next World Championships &ndash; again on home soil in 2025.
&ldquo;I have a strong desire to win in Tokyo because I couldn&rsquo;t win in Budapest,&rdquo; he said. &ldquo;It will be held in Japan so I am looking forward to having many people watching our race as I prepare for the Games.&rdquo;
Bonfim is in top form after recording a 1:17:44 PB in Taicang at the first Gold Tour race of the year. He was third in Podebrady last month in 1:18:50, and looked on course to share gold with Viviane Lyra in the inaugural mixed marathon relay at the World Athletics Race Walking Team Championships in Antalya last month until a late penalty demoted them to fifth.
If not this illustrious pair around the 1.2km loop in Teatralny Square and Piłsudskiego Square, who else?
Zhang Jun won the Taicang race in 1:17:26, his third sub-78-minute clocking at the distance and a PB. Wang Zhaozhao recorded an impressive 1:17:48 in Taicang also, but faded to 57th in Antalya. The Chinese pair won&rsquo;t be short of friendly company: seven of their teammates will toe the line in Warsaw.
Australia&rsquo;s Declan Tingay clocked a PB of 1:18:30 in Budapest, and in Antalya was key to ensuring a second Australian team will toe the line in the Olympic mixed marathon relay.
Team-mate Rhydian Cowley, partnering Jemima Montag, finished some way ahead of Tingay in Antalya. Cowley&rsquo;s preparation for Paris looks very much on song with a 1:18:33 clocking in Taicang; not to mention 38:13.51 on the track over 10,000m at the Australian Championships in April, a result bettered by Tingay in 38:07.88 for the win.
The sentimental cheers of the morning are headed the way of Dawid Tomala. The hometown hero and Olympic 50km gold medallist was a non-finisher in Dudince in March, but he recovered to partner Katarzyna Zdzieblo to an Olympic mixed relay place in Antalya. The 34-year-old&rsquo;s 20km PB of 1:20:30 dates back to 2013.
Kimberly Garcia, winner over 20km in Warsaw last year, had initially opted to contest the 10km this weekend, but the double 2022 world champion has since pulled out of that, concentrating instead on recovery from her World Race Walking Team Championships win in Antalya.
All eyes will be on Montag and a clutch of talented Chinese race walkers, all of whom finished inside 1:28 in Taicang. The contingent includes four-time world champion Liu Hong, 2012 Olympic champion Qieyang Shijie, plus Ji Haiying and Shi Yuxia, who finished sixth and seventh respectively in Antalya.
Now a mother anticipating a 37th birthday next week, Liu&rsquo;s appetite for global success still burns strong. The 2016 Olympic champion has won races all over the world, and she recently clocked 1:26:47 in Taicang &ndash; her fastest time in three years &ndash; to underline her current form.
Montag made a breakthrough statement in 2023 with silver at the World Championships in 1:27:16. The 26-year-old medical student followed that up by setting an Oceanian record of 1:27:09 in February, and then finished sixth alongside Cowley in Antalya&rsquo;s mixed marathon relay. She too knows all about performing on foreign shores.
Poland&rsquo;s double 2022 world silver medallist Katarzyna Zdziebło will get huge support on the course, and there&rsquo;s a welcome return to competition for Antigoni Ntrismpioti. The 40-year-old from Greece has raced just once this year, clocking 44:39.83 on the track for 10,000m in Canberra, but the 2022 double European champion has pedigree in spades.
She will need to be with Chinese vests and Montag alongside ready to set a fast pace.

Global gold medallists Liu and Yamanishi among the contenders in Warsaw

World champion Sha&rsquo;Carri Richardson and world indoor 60m champion Christian Coleman will contest the 100m at the Prefontaine Classic while global medallists Erriyon Knighton, Letsile Tebogo and Kenny Bednarek will clash in the men&rsquo;s 200m at the Wanda Diamond League meeting in Eugene on Saturday 25 May.
Richardson sped to victory over 100m at last year&rsquo;s World Championships in Budapest, setting a PB of 10.65 to equal the championship record, and followed it by anchoring the USA to gold in the 4x100m.
The US sprinter will take on world indoor 60m champion Julien Alfred of St Lucia and African record-holder Marie-Josee Ta Lou of the Ivory Coast.
Coleman, who claimed the Diamond Trophy over 100m last year by equalling the world lead of 9.83, will be joined in the men&rsquo;s event by African record-holder Ferdinand Omanyala of Kenya and world indoor 60m bronze medallist Ackeem Blake of Jamaica.
The men&rsquo;s 200m in Eugene will also be highly competitive as Knighton, Tebogo and Bednarek take to the line.
Knighton &ndash; who has a lifetime best of 19.49 &ndash; took silver in that discipline at last year&rsquo;s World Championships, earning his second global medal before even turning 20.
Botswana&rsquo;s Tebogo is similarly prodigious. He won back-to-back world U20 titles over 100m in 2021 and 2022, then claimed world 100m silver and 200m bronze in Budapest last year, just weeks after turning 20. His PB of 19.50 is just 0.01 shy of Knighton&rsquo;s.
Bednarek claimed Olympic silver in 2021 and followed it with world silver in 2022. Along with Tebogo, Bednarek is one of a small number of men who have broken 10 seconds for 100m, 20 seconds for 200m and 45 seconds for 400m.

World champion Sha’Carri Richardson and world indoor 60m champion Christian Coleman will contest the 100m

Sprint headliners confirmed for Eugene

Seven athletes will represent the Olympic Refugee Team in athletics at the Paris 2024 Olympic Games.
The squad includes distance runner Tachlowini Gabriyesos, who placed 16th in the marathon at the last Olympic Games in Tokyo &ndash; the highest ever finish by a refugee athlete at a global championships.
Other endurance athletes on the team include 800m specialists Perina Lokure Nakang and Musa Suliman, 5000m runner Jamal Abdelmaji Eisa Mohammed and middle-distance runner Farida Abaroge, who made her Athlete Refugee Team debut at the recent World Cross Country Championships in Belgrade.
Dorian Keletela, who in 2021 became the first sprinter to represent a refugee team at a global championships, will contest the 100m. And Mohammad Amin Alsalami, who last year became the first field event athlete to represent a refugee team at a global championships, has been named in the long jump.
&ldquo;These athletes are an enrichment to our Olympic Community, and to our societies,&rdquo; said IOC President Thomas Bach. "With their participation in the Olympic Games, they will demonstrate the human potential of resilience and excellence. This will send a message of hope to the more than 100 million displaced people around the world.&rdquo;

The composition of the teams may be slightly different, but a USA-Netherlands showdown in the mixed 4x400m &ndash; less than a year on from their dramatic duel at the World Championships &ndash; could provide one of the highlights of the World Athletics Relays Bahamas 24.
On that occasion in Budapest last year, Femke Bol of the Netherlands was locked in battle with USA&rsquo;s Alexis Holmes on the final leg. In the closing metres, Bol lost her footing and crashed to the ground, while Holmes maintained her momentum to carry USA to victory in a world record of 3:08.80.
<div><a href="https://worldathletics.org/competitions/world-athletics-relays/bahamas24/where-to-watch" target="_blank" rel="noopener"><img style="max-width: 900px; width: 100%; display: block;" src="https://assets.aws.worldathletics.org/66341327d6042ffd2e3b73cc.jpg" alt="World Relays where watch banner small" /></a></div>
Bol and Holmes have both been named in the women&rsquo;s 4x400m, not the mixed event, for Nassau, so fans may still be treated to a rematch of sorts between the pair. But without world indoor champion Bol&rsquo;s foot speed in their armoury, the Netherlands may not be quite as formidable in Nassau.
Just one member of the world record-breaking quartet, Matthew Boling, will feature on USA&rsquo;s team for the World Relays, and he&rsquo;ll be joined by Olympic 4x400m champion Lynna Irby-Jackson.
The Dominican Republic &ndash; winners of the world title in 2022 ahead of the Netherlands and USA &ndash; will be bolstered by the presence of world 400m champion Marileidy Paulino, who has already notched up Diamond League victories in Xiamen and Suzhou this year. Alexander Ogando, who was also part of the triumphant 2022 squad, is also on the team for Nassau.
Since winning the Olympic title in 2021, Poland hasn&rsquo;t quite been able to replicate that form. They placed fourth in the mixed relay at the 2022 World Championships, then eighth at the 2023 edition. World silver medallist Natalia Kaczmarek and 2018 European champion Justyna Swiety-Ersetic add strength to their squad, but both may also be called up for the women&rsquo;s 4x400m so may be running on tired legs for the mixed event.
The biggest cheers, though, will be reserved for The Bahamas, who won the inaugural mixed 4x400m when the World Relays was last held in Nassau. Three members of that quartet &ndash; including Olympic 400m champions Steven Gardiner and Shaunae Miller-Uibo &ndash; feature on the host nation&rsquo;s team for this year&rsquo;s edition, and they will aim to strike gold on home turf again.
Great Britain &amp; Northern Ireland claimed silver behind the USA at last year&rsquo;s World Championships, and they&rsquo;re intent on challenging for another podium place in Nassau after naming some of their best one-lap sprinters for the mixed 4x400m.
Czechia&rsquo;s mixed relay pool includes the same four athletes that claimed bronze in this event in Budapest last year, so they could well be a danger again.
Jamaica earned world silver in this event at the 2019 World Championships, but haven&rsquo;t made a global podium since then. They boast strong depth in both the men&rsquo;s and women&rsquo;s 400m, so undoubtedly have the potential to be in the hunt in Nassau.
France and Belgium, meanwhile, were just shy of the medals in Budapest, so they&rsquo;ll head to Nassau with plenty of motivation, as will defending champions Italy.
Other contenders include Bahrain, Botswana and a Canadian squad that features world 800m champion Marco Arop.

World Athletics Relays Bahamas 24

The composition of the teams may be slightly different, but a USA-Netherlands showdown in the mixed 4x400m could provide one of the highlights of the World Athletics Relays Bahamas 24

WRE Bahamas 24 preview: scene set for mixed 4x400m showdown

The World Athletics Relays Bahamas 24 offers USA&rsquo;s 4x400m men the chance to maintain an unbeaten run in Nassau, but there are a number of nations ready to challenge for top spot this weekend (4-5 May).
After the first three editions of the World Athletics Relays &ndash; all held in The Bahamas, with US men&rsquo;s 4x400m teams winning at each &ndash; the 2019 title went to Trinidad and Tobago in Yokohama, before the Netherlands clinched the crown in Silesia in 2021, when USA did not field a team.
Since then, each of the three major outdoor global titles have been won by USA. But with so much at stake &ndash; including Olympic places for 14 teams &ndash; competition is set to be fierce.
<div><a href="https://worldathletics.org/competitions/world-athletics-relays/bahamas24/where-to-watch" target="_blank" rel="noopener"><img style="max-width: 900px; width: 100%; display: block;" src="https://assets.aws.worldathletics.org/66341327d6042ffd2e3b73cc.jpg" alt="World Relays where watch banner small" /></a></div>
Entered for the US this time is Bryce Deadmon, who formed part of the Olympic gold medal-winning team in Tokyo and the quartet that claimed the world title in Oregon in 2022. Champion Allison ran the anchor leg in Oregon, while Christopher Bailey ran the heats in Budapest, where USA retained the world title, and brought the baton home to secure world indoor silver in Glasgow in March.
Gold in Glasgow was won by Belgium, anchored by Alexander Doom, who became the first man to win the 400m and 4x400m at the same World Indoor Championships. The team &ndash; which also featured Jonathan Sacoor, Dylan Borlee and Christian Iguacel &ndash; pipped USA by 0.06 to retain the title.
That quartet has been named for Nassau, on a squad that inevitably includes two other Borlee brothers, Jonathan and Kevin &ndash; the latter having joined Dylan on the 2019 and 2022 world bronze medal-winning teams.&nbsp;
The Borlee brothers were also part of the squad &ndash; along with Doom and Sacoor &ndash; that finished fourth at the Tokyo Olympics behind USA, Netherlands and Botswana. Three members of that Dutch silver medal-winning team are named for Nassau: Terrence Agard, Ramsey Angela and Liemarvin Bonevacia. They also formed part of the team to claim world indoor bronze in Glasgow, while Angela and Bonevacia helped Netherlands to their World Relays win in 2021.
Trinidad and Tobago&rsquo;s 2017 world 4x400m gold medallist Jereem Richards was on the victorious World Relays squad in 2019 along with Asa Guevara, and they team up again this weekend.
As well as Olympic bronze in Tokyo, Botswana &ndash; second at the World Relays in 2017 and third in 2021 &ndash; made the past two world finals, though the team was disqualified in Budapest. In the squad this time are world 100m and 200m medallist Letsile Tebogo, who ran a world 300m best of 30.69 in February and a 400m PB of 44.29 in March, and world 400m leader Bayapo Ndori, who clocked 44.10 last month.
Other recent major medallists Jamaica, France and Great Britain &ndash; who respectively claimed 2022 world silver, 2023 world silver and 2023 world bronze &ndash; will also want to make a statement as they seek to secure their Olympic spots.&nbsp;
The Jamaican squad includes Rusheen McDonald, the 2013 world and 2016 Olympic relay silver medallist who helped his nation to finish fourth at last year&rsquo;s World Championships. The French team, with a home Olympics in their sights, features three of the four world silver medallists. Two-time world 400m medallist Matthew Hudson-Smith is among those on the British squad.
Entered for the host nation in both the men&rsquo;s and mixed 4x400m is Steven Gardiner, the Olympic and 2019 world 400m champion, and he&rsquo;ll hope to help his team improve on their two runner-up finishes in this event on home soil in 2014 and 2015.
Zambia heads to Nassau as the fastest nation in the world so far this year, having clocked a national record of 2:59.12 to win at the All-African Games in Accra in March. Botswana was second and Nigeria third in Accra, and they could all clash again in Nassau.
Canada&rsquo;s entry list includes world 800m champion Marco Arop and 19-year-old Christopher Morales Williams, who ran 44.49 for the fastest ever indoor 400m in Arkansas in February.
Also among those seeking Olympic qualification will be recent major finalists Japan, who finished second at the last World Relays, plus India, Italy and Poland.

WRE Bahamas 24 preview: global medallists in men's 4x400m rematch

The US women&rsquo;s 4x400m squad will be hoping that a return to Nassau for the World Athletics Relays Bahamas 24 will be a lucky omen.
For the first three editions of this competition &ndash; all of which were held in the Bahamian capital &ndash; USA won the women&rsquo;s 4x400m. But ever since the event has moved out of the Caribbean, the women&rsquo;s 4x400m title has been won by other nations.
<div><a href="https://worldathletics.org/competitions/world-athletics-relays/bahamas24/where-to-watch" target="_blank" rel="noopener"><img style="max-width: 900px; width: 100%; display: block;" src="https://assets.aws.worldathletics.org/66341327d6042ffd2e3b73cc.jpg" alt="World Relays where watch banner small" /></a></div>
In 2021 &ndash; a year in which USA and Jamaica opted not to send a team &ndash; Cuba was the surprising victor, finishing just ahead of Poland and Great Britain &amp; Northern Ireland.
Normal order was restored soon after, with USA winning Olympic gold later that year and then winning world gold in 2022. But it&rsquo;s the Netherlands who head to Nassau as the reigning world championships indoors and out, following their victories in Budapest in 2023 and Glasgow in 2024.
Granted, their World Championships victory last year came after the USA was disqualified for a baton exchange that occurred outside the zone. But the Dutch squad triumphed again at this year&rsquo;s World Championships, beating the USA fair and square.
Femke Bol and Lieke Klaver, the world indoor 400m gold and silver medallists respectively, always pack a powerful punch for the Netherlands. Meanwhile, Alexis Holmes &ndash; who anchored the USA to mixed 4x400m victory in Budapest just moments after Bol fell &ndash; is the standout performer on the USA women&rsquo;s 4x400m team.
Jamaica is the only team to have reached the podium in this event at the past three outdoor global championships, so they cannot be overlooked. Great Britain &amp; Northern Ireland, meanwhile, have earned three global bronze medals in the past two years, so will also be keen to challenge again.
World 400m silver medallist Natalia Kaczmarek and 2018 European champion Justyna Swiety-Ersetic feature on Poland&rsquo;s team, but both have also been selected for the mixed event.
Canada has been quietly consistent in recent years, placing fourth at the past three global championships. Although they&rsquo;ve missed out on medals, they consistently outperform their pre-event form on paper.
Belgium has been creeping ever closer to a global championships podium finish, placing seventh at the Tokyo Olympics, sixth at the 2022 World Championships, fifth at the 2023 edition, and fourth at the recent World Indoor Championships.
Other teams to look out for include African Games champions Nigeria, France and India.

500 days to go! WCH Tokyo 25 ticket programme announced

Three global championships have been held since the last edition of the World Relays, and each one has produced a different winner of the men&rsquo;s 4x100m.
All three of those gold-medal-winning nations will clash at the World Athletics Relays Bahamas 24 in what looks set to be one of the most competitive races of the weekend.
Italy pulled off a surprised triumph at the 2021 World Relays in Silesia. At the time, it seemed as though they benefitted from a depleted field, given that the pandemic meant that relay powerhouses USA and Jamaica did not send a team.
<div><a href="https://worldathletics.org/competitions/world-athletics-relays/bahamas24/where-to-watch" target="_blank" rel="noopener"><img style="max-width: 900px; width: 100%; display: block;" src="https://assets.aws.worldathletics.org/66341327d6042ffd2e3b73cc.jpg" alt="World Relays where watch banner small" /></a></div>
But at the Olympic Games later that year, with all countries fielding their best squads, Italy proved their relay success was no fluke as they powered to victory in 37.50.
The four men who stood atop the podium on that occasion in Tokyo &ndash; Lorenzo Patta, individual Olympic 100m champion Marcell Jacobs, Eseosa Desalu and Filippo Tortu &ndash; have been named on Italy&rsquo;s team for this year&rsquo;s World Relays.
Like any team lining up in Nassau, their main goal will be to ensure their qualification for the Paris 2024 Olympic Games, where they&rsquo;ll be aiming to defend their Olympic title.
But a strong US squad also heads to Nassau highly motivated to perform well in the men&rsquo;s 4x100m.
The sprints superpower struck gold in the 4x100m at the World Championships in Budapest last year. World 100m and 200m champion Noah Lyles anchored the US to relay victory ahead of Italy in the Hungarian capital last year, but he is the only member of that victorious quartet who&rsquo;ll be in action this weekend.
The other members of the USA&rsquo;s World Relays squad are certainly no slouch, though. Olympic 200m silver medallist Kenny Bednarek, world 200m leader Courtney Lindsey and NCAA medallist Pjai Austin &ndash; all of whom have identical 100m PBs of 9.89 &ndash; add strength to the US team.
All four men who carried Canada to 4x100m victory at the 2022 World Championships &ndash; including Olympic 200m champion Andre De Grasse &ndash; will also be in action. The Olympic silver medallists will be keen to make amends after missing out on the World Championships final last year.
Jamaica has earned just one medal &ndash; 2023 world bronze &ndash; from the past three global championships, but there&rsquo;s no denying they have the speed and depth to challenge for major titles. Their squad for Nassau includes three sub-10-second sprinters, including world indoor bronze medallist Ackeem Blake, world finalist Ryiem Forde and World University Games champion Kadrian Goldson.
Great Britain &amp; Northern Ireland, who took world bronze in 2022 and finished just 0.04 shy of the podium at last year&rsquo;s World Championships, have also fielded a strong team of numerous sub-10-second performers. World bronze medallist and 2023 world leader Zharnel Hughes will be joined by the likes of Reece Prescod, Eugene Amo-Dadzie, CJ Ujah and Nethaneel Mitchell-Blake.
Olympic bronze medallists China head to Nassau as the fastest nation in the world this year. Their quartet of Su Bingtian, Xie Zhenye, Wu Zhiqiang and Chen Jiapeng clocked 38.28 at the East Coast Relays last weekend, and all four of those sprinters will be in action in Nassau.
Many other teams will be hopeful of claiming a place in the final &ndash; or at least a position in the top 14 placed teams that will earn Olympic qualification.
Nigeria won the African Games title last month, while Thailand took a surprise victory at last year&rsquo;s Asian Championships. Japan placed second at the last World Relays in 2021 and finished fifth at the World Championships last year. Brazil, meanwhile, were the surprise winners at the 2019 World Relays.
South Africa, France and the Netherlands all have the potential to earn a place in the 4x100m final too.
The main goal, however, will be to simply get the baton around safely.

WRE Bahamas 24 preview: clash of global title-winning teams in men's 4x100m

There&rsquo;s so much to race for at the World Athletics Relays Bahamas 24 and in the women&rsquo;s 4x100m, athletes from 30 teams will be battling it out for Olympic places, prize money and bragging rights.
For all five of the events in Nassau, the top 14 teams in each will automatically qualify for the Paris 2024 Olympic Games. Since the last edition of the World Athletics Relays, either the United States or Jamaica have won the three major global titles on offer, and they&rsquo;ll renew their rivalry this weekend (4-5 May).
<div><a href="https://worldathletics.org/competitions/world-athletics-relays/bahamas24/where-to-watch" target="_blank" rel="noopener"><img style="max-width: 900px; width: 100%; display: block;" src="https://assets.aws.worldathletics.org/66341327d6042ffd2e3b73cc.jpg" alt="World Relays where watch banner small" /></a></div>
Jamaica claimed the Olympic crown ahead of USA in Tokyo, before USA won world gold in Oregon and retained the title in Budapest, both times beating Jamaica.&nbsp;
In Nassau, the US team will feature four of the athletes who helped their nation to top of the podium in Budapest: individual 200m silver medallist Gabby Thomas and Tamari Davis, who both raced in the final, are joined by heat runners Tamara Clark and Melissa Jefferson. Mikiah Brisco, who formed part of a US team that ran a world-leading 41.94 in Gainesville earlier this month, and Celera Barnes add further strength to the squad.
While the Jamaican team also boasts much quality, just two of the team members from those three global finals return. Natasha Morrison and Remona Burchell both ran in the heats in Tokyo, while the consistent Morrison &ndash; also a world relay gold medallist in Beijing and Doha &ndash; led off for Jamaica in Budapest last year.
The squad is not lacking speed, however, and their teammate Alana Reid, the&nbsp;world U20 200m bronze medallist,&nbsp;set a national U20 100m record of 10.92 last year.
But in Nassau it will be far from a two-way fight. Great Britain bagged bronze in Tokyo and Budapest and the squad this time includes returning team members Asha Philip, Imani Lansiquot, Bianca Williams and Annie Tagoe. Lansiquot has already run 11.02 &ndash; just 0.03 off her PB &ndash; this season.
The other medallist from those three major finals is Germany, the 2017 World Relays winner. Two of the four 2022 bronze medal-winning team members are in Nassau: Rebekka Haase and Gina Luckenkemper.
Italy won at the last edition of the World Relays in Silesia in 2021, and two members of that team &ndash; Anna Bongiorni and Irene Siragusa &ndash; return to defend the title.
Other teams who will be pushing for the podium as well as Olympic places will be Poland, featuring world indoor 60m silver medallist Ewa Swoboda, and Cote d'Ivoire, with multiple major medallist Marie-Josee Ta Lou, plus their fellow 2023 world finalists Netherlands and Switzerland.
France, with Gemima Joseph who recently ran a 100m PB of 11.04, will want to secure that spot for the home Olympics.
The Canadian squad stars the new national record-holder Audrey Leduc, who ran 10.96 just over a week ago, while the Australian team includes Torrie Lewis, the 19-year-old who won the 200m at the Diamond League meeting in Xiamen, alongside her fellow area record-setting teammates Bree Masters, Ella Connolly and Ebony Lane.
The host nation&rsquo;s squad features 60m hurdles world champion and world record-holder Devynne Charlton and Charisma Taylor, who finished sixth in the 60m hurdles and the triple jump on the same day at the World Indoor Championships.
Ecuador's 4x100m women made history in Silesia as they achieved their nation&rsquo;s first ever Olympic relay spot by finishing fifth at the World Relays. Three years on, Angela Gabriela Tenorio and Gabriela Anahi Suarez are back, hoping to help their nation now secure a place for Paris.
Like Cote d'Ivoire, teams from Austria, Estonia, Hungary and Liberia are competing at the World Athletics Relays for the first time.

There’s so much to race for at the World Athletics Relays Bahamas 24 and in the women’s 4x100m, athletes from 30 teams will be battling it out for Olympic places, prize money and bragging rights

WRE Bahamas 24 preview: rivalries renewed in women's 4x100m

Multiple global gold medallists &ndash; including Noah Lyles, Femke Bol and Bahamian stars Shaunae Miller-Uibo, Steven Gardiner and Devynne Charlton &ndash; will be among the athletes in action at the World Athletics Relays Bahamas 24 on 4-5 May.
The competition holds extra significance, as it is the main qualifying event for relay events at the Paris 2024 Olympic Games.
Competition takes place at the Thomas A. Robinson National Stadium in Nassau.

Building on its experience in measuring air quality in stadiums, the Health &amp; Science Department at World Athletics has taken a new step in protecting the health of athletes.&nbsp;
Following the installation of a <a href="https://kunakair.com/" target="_blank" rel="noopener">Kunak</a> air quality sensor at the Parc des Sports Charles Ehrmann stadium in Nice, a <a href="https://www.lifyair.com/en/" target="_blank" rel="noopener">Lify-Air</a> pollen measurement sensor has also been added, meaning athletes who use the stadium now have access to essential hyperlocal information to help them manage their respiratory health.&nbsp;
Exposure to airborne pollen is a health concern during outdoor sporting events and it poses a risk to large numbers of athletes who may suffer an allergic response. Asthma and related allergy symptoms are commonly reported by athletes after competing in endurance events. Almost half the runners questioned (47%) reported upper respiratory symptoms post marathon, illustrating the extent of respiratory issues during and after running events (Robson-Ansley et al. 2012).&nbsp;
A study conducted during the Comrades Marathon between 2014 and 2019 shows that respiratory disease (asthma, allergenic rhinitis) was the most frequent reported chronic disease (2.4%) (Brill et al. 2023).&nbsp;
Air pollution, greenhouse gases and global warming are the main causes of the increase in pollen allergy. Air pollution increases the allergen content of pollen and damages its surface, releasing more allergens (Gisler 2021) and likely exacerbating respiratory diseases experienced during the peak of the pollen season (Orellano et al. 2017). Consequently, the prevalence of respiratory allergic diseases among athletes can be viewed in the context of increased exposure to outdoor atmospheric pollutants (particulate matter (PM10, PM2.5) and allergens (Helenius et al. 1997). All of these factors cause changes in the flowering of plants and in the structure of pollen grains, resulting in a higher incidence of symptoms.
For allergic athletes, pollen and air quality information is the cornerstone of pollen allergy management. Pollen allergy bulletins and forecasts are the best way to limit their exposure to allergens, and to adapt their treatments to this level of exposure.&nbsp;
In order to address these requirements, they must understand the timing, quantity, and specific type of pollen they are exposed to or might be exposed to. It's very likely that airborne pollens are not evenly distributed over the territory due to differences in topography and vegetation, and that each athletics stadium therefore has its own specificity.&nbsp;
With this project, the Health &amp; Science Department hopes that hyperlocal data recording will help to educate athletes about environmental risks and enable them to minimise their level of exposure and maintain optimum performance levels.

Athlete respiratory health in the spotlight thanks to new sensor in Nice

USA&rsquo;s Taliyah Brooks retained her Multistars heptathlon title by equalling her PB of 6330, while Belgium&rsquo;s Jente Hauttekeete secured his first decathlon victory at a World Athletics Combined Events Tour Gold meeting, winning with 8020 in Brescia on Sunday (28).
Brooks began the defence of her heptathlon title with the day&rsquo;s fastest 100m hurdles, clocking 13.14 into a headwind (-2.3m/s). But there was disappointment for China&rsquo;s Asian Games champion Zheng Ninali, as she was disqualified.
The high jump was up next and Brooks cleared 1.77m &ndash; the second-best performance of the day behind Bianca Salming&rsquo;s 1.83m &ndash; before throwing 13.11m in the shot. Austria&rsquo;s 2018 world indoor pentathlon silver medallist Ivona Dadic, returning from injury, launched the implement 14.55m to top that event.
Brooks ended day one with a leading 200m time of 23.92, putting her 220 points ahead of Norway&rsquo;s Ida Eikeng.
The second day started well for Brooks as she extended her lead by topping the long jump with 6.52m. It was also a strong discipline for Sweden&rsquo;s Lovisa Karlsson (6.47m) and Switzerland&rsquo;s Katelyn Adel (6.41m), both of whom set PBs to move into second and third overall respectively.
Eikeng excelled in the javelin, launching her spear out to 51.62m to move up to third overall. Ireland&rsquo;s Kate O&rsquo;Connor, twice a runner-up at Multistars, moved into second place overall thanks to her 49.28m effort.
Brooks was further down the field with 38.53m, but she still ended the event with a lead of almost 200 points with just the 800m to go.
Adel, who had put together the series of her life this weekend, continued her momentum into the 800m, smashing her PB to win it in 2:12.66. Salming followed in 2:13.49 and Brooks &ndash; buoyed by the knowledge she had the title in the bag &ndash; was close behind in 2:13.81, a PB.
It meant that the US heptathlete successfully defended her title by equalling the 6330 PB she set when winning at Multistars last year.
O&rsquo;Connor, who clocked 2:15.14 in the final event, achieved her third Multistars runner-up finish with 6104 and Adel placed third with 6082 &ndash; a PB by more than 300 points. Karlsson just missed the podium, but was also rewarded with her first 6000-point tally, scoring 6051.
&ldquo;I&rsquo;m excited to come here, get a decent score and walk away healthy,&rdquo; said Brooks. &ldquo;I got the exact same score as last time. Last year I was really happy with my 800m, and this year is the same &ndash; I set a PB by two seconds. It&rsquo;s something I&rsquo;ve been working really hard on.&rdquo;
<h2>Hauttekeete times challenge to perfection</h2>
Jente Hauttekeete may not have topped the leader board in any of the individual disciplines, but the 22-year-old&rsquo;s overall consistency in the decathlon led to him taking the title with 8020, the second-best score of his career.
Switzerland&rsquo;s Nino Portmann took an early lead, winning the first 100m heat in 10.91. Belgium&rsquo;s Robin Bodart won his heat in 10.93 for the day&rsquo;s second-fastest time and Teo Bastien led heat three in 11.04 to put him fifth overall after one event, just ahead of Hattekeete (11.06).
Bastien, the 2021 European U20 bronze medallist, soared into the lead after the next event, going close to his long jump PB with a leap of 7.82m. Hauttekeete, the world U20 heptathlon record-holder, was sixth at that stage after leaping 7.37m.
A 14.12m throw moved Hauttekeete up to fourth following the shot put, with Bastien holding on to the lead thanks to an outdoor PB of 13.84m. Czechia&rsquo;s 2016 European silver medallist Adam Helcelet made his presence felt at this stage, launching the shot 15.31m to place him fifth overall, with Yuma Maruyama and Jose Fernando Ferreira Santana completing the top five.
Hauttekeete and Santiago Ford both soared clear at 2.01m in the high jump, which moved them to second and third respectively behind Bastien (1.95m). His lead was 45 points at that stage but Hauttekeete ran 49.16 to Bastien&rsquo;s 50.10 in the 400m &ndash; the final event of the day &ndash; to take the gap to just a single point at the half way stage.
Ferreira Santana dominated the 110m hurdles at the start of day two and was the only man to finish inside 14 seconds, clocking 13.88. Hauttekeete took a brief lead thanks to his 14.44 clocking, while Bastien managed 14.51, but the French all-rounder responded in the next event, throwing a discus PB of 43.49m to regain the lead.
Hauttekeete threw 40.13m, and Chile&rsquo;s Santiago Ford moved up the leaderboard into third after sending his disc flying out to 47.84m, the best of the day. Murayama, meanwhile, set his third PB of the competition with 46.21m.
Belgium&rsquo;s Thomas van der Plaetsen, the 2016 European champion, was a non-starter for the next discipline. But his compatriot Bodart ensured a Belgian still topped that event, vaulting 5.15m. Bastien was next best, extending his lead thanks to a 5.05m clearance, while Hauttekeete remained in contention with 4.85m.
The discipline ended with disappointment for Murayama, though, as he landed awkwardly on his final attempt at 4.65m and was forced to exit the competition.
Hauttekeete threw a PB of 56.04m in the javelin, but he was bumped down to third place after Ferreira Santana launched his spear out to 67.47m. Bastien increased the gap between him and Hauttekeete, throwing 56.98m.
Bastien had a 138-point lead over Hauttekeete going into the 1500m. Although the Belgian was a far superior 1500m runner, he still needed to finish 25 seconds ahead of Bastien to secure the victory.
Switzerland&rsquo;s Andrin Huber was a comfortable winner of the 1500m, clocking 4:23.99, then Estonia&rsquo;s Risto Lillemets crossed the line a few seconds later, closely followed by Hauttekeete (4:30.80). Bastien, meanwhile, finished outside five minutes (5:02.75).
It meant that Hauttekeete took the victory with 8020 from Lillemets (7971). Bastien held on for third place with 7963, just 26 points ahead of Ferreira Santana.
&ldquo;I just kept going and fought until the end and now I&rsquo;m here in first position,&rdquo; said Hauttekeete. &ldquo;I knew I needed to finish 25 seconds ahead of Bastien and I knew that would be tough. But it&rsquo;s never over until the end.&rdquo;
