Bolt confirms Golden Spike appearance
Usain Bolt will compete again at the Golden Spike in Ostrava on June 17.
Organisers say the six-time Olympic gold medallist has yet to decide whether to run the 100 or 200 metres.
Bolt previously said his goal for 2014 was to break his own 200m world record of 19.19 seconds.
Bolt says "Ostrava is a fast track when the weather is good. I look forward to good weather and good performances in 2014."
The Jamaican will race for the seventh time at the meet, which is part of the IAAF World Challenge series.
