Usain Bolt will again run in Ostrava at the Golden Spike meet.
The Olympic champion will race for the sixth time at the meet, which is part of the new IAAF World Challenge series. The meet is scheduled for May 25.
Bolt has already committed to running the 100 at a couple of European meets in this year. He will compete in Rome on May 31, and at another Diamond League meet in Oslo on June 7 before returning to Jamaica for the national trials ahead of the London Olympics.
Last year, Bolt won the 100 at the Golden Spike, finishing in 9.91 seconds.
Bolt swept the 100 and 200 at the 2008 Beijing Games and helped Jamaica to gold in the 4x100 relay.
