Usain Bolt wins (again) but fails to run under 10sec

Usain Bolt won the 100m sprint at the Golden Spike meeting in Ostrava.

The Jamaican, who is expected to retire at the World Championships in London in August, failed to run a sub-10 second time for the second race in succession.

In characteristic style Bolt was a hint shaky out of the blocks but once his long legs began to beat out a rhythm with 40m to go he stretched away from second-placed Yunier Perez, from Cuba.

The three-time Olympic 100m champion won in 10.06 seconds.

In other events on the night Britain's Mo Farah won the 10,000m in 27 minutes and 12 seconds, and South Africa's Wayde van Niekerk set an electrifying 300m world record of 30.81, beating Michael Johnson's 30.85 set in 2000.
