Usain Bolt confirmed his special appearance at 49th Ostrava Golden Spike Meeting on May 27 in Czech Republic. This is a flashback to last year's Ostrav Golden Spike.

Melbourne, Australia - David Rudisha had his first race over 800m for 2010 as the IAAF World Challenge 2010 kicked of at the Melbourne Track Classic on Thursday night, and produced something special again. He predicted a 1:43 and delivered on the talk, running 1:43.15. Ryan Gregson took almost a full second off his previous best in second place, but his 1:46.04 saw him almost a full three seconds adrift.
