US pair Ajee Wilson and Chanelle Price have enjoyed breakthroughs indoors this winter to occupy the top two positions on the 2014 world list with 2:00.43 and 2:00.48, respectively, after their one-two finish at the US Indoor Championships.
Both are making their debuts in the event and Wilson, still only 19, will be chasing a senior crown to add to her world junior and world youth titles.
Another young athlete, Great Britain’s 20-year-old Laura Muir, goes into the event full of confidence following a 2:00.94 best in January and an impressive victory over 1500m in Birmingham.
Home favourite Angelika Cichocka has been rounding into form nicely. A finalist over 1500m in Istanbul two years ago, Cichocka recently produced her second-best indoor 800m performance of 2:01.14 to win the Polish indoor title at the ERGO Arena in Sopot.
European indoor champion Nataliia Lupu cannot be discounted, nor can Russian indoor champion Anna Shchagina.
