PRAGUE (AP) - Usain Bolt will again run at the Golden Spike meet in the Czech city of Ostrava.
The six-time Olympic champion will race for the seventh time at the meet, which is part of the new IAAF World Challenge series. It is scheduled for June 27.
This time, Bolt will join Jamaican teammate Yohan Blake, the 2011 world champion in the 100 meters, for the 4x100-meter relay.
Blake is expected to be Bolt's toughest challenger at the Aug. 10-18 world championships in Moscow. The other two names on the relay team have yet to be named.
Bolt defended his titles in the 100 and 200 meters at last year's London Olympics and also anchored the Jamaicans to victory in the 4x100 relay in 36.84 seconds to set a world record.
