It will be the second time that the Olympic and World champion will contest the 100m at this IAAF World Challenge meeting and his second race over the distance this season.
"I ran 9.77 seconds in Ostrava in 2009 with a +2.1 wind," said Bolt, whose World record of 9.58 was set later that summer at the World Championships in Berlin. "I hope the wind and the weather conditions are favourable this year."
"My first 100 metres of the season will be in Rome (36 May), then Ostrava and then a 200 metres in Oslo,” Bolt said.
His appearance at the end of the month will mark the fourth time that the 24-year-old Jamaican has competed in this eastern Czech city. In addition to his 2009 100m victory, he twice contested the 200m - 20.28 in 2006 and 19.83 in 2008 - and in 2010 ran the 300m, clocking 30.97, the second fastest performance ever.
Other dates confirmed for Bolt thus far include Samsung Diamond League fixtures in Paris (8 July) and Monaco (22 July) where he'll run the 200m and 100m respectively.
