Ohuruogu's key target will be 2009 World champion Sanya Richards-Ross, who claimed the World Indoor title in Istanbul in March. The field also includes solid European opposition with Czech 2011 European Indoor champion Denisa Rosolova (50.84), Italian record holder Libania Grenot (50.30), former European sprint champion Muriel Hurtis of France who switched to the 400m (51.41), another Briton Shana Cox (50.84), and Ukrainian Barcelona 6th placer Antonina Yefremova (50.69).
Russian Tatyana Lysenko, the 2011 World champion, has been added to the already strong women's Hammer Throw field which boasts both Betty Heidler and Anita Wlodarczyk, the current and past World record holders, respectively, and both former World champions.
In the women's 100m Hurdles, where organizers are hoping for an assault on one of the meetings oldest records - 12.65 from 1980 - the newest names are 2011 European indoor champion Carolin Nytra of Germany, UK record holder Tiffany Porter, and this year's US indoor champion Kristi Castlin. Kellie Wells, Priscilla Lopes-Schliep and Lolo Jones, who'll be making her season debut, have been previously announced.
A special addition to this year's meet will be men's 4x100m Relay with South Africa, Canada, Poland and home team Czech Republic taking part. There may also be a Jamaican foursome and an all-star team added as well. For national teams the opportunity provides a good possibility to achieve quality times for olympic qualification.
