Jonnie Peacock relishes rivalry at IPC World Championships

British sprinter Jonnie Peacock says his rivalry with American Richard Browne is fantastic for disability sport, after he added a world title to his 2012 Paralympic gold medal.

The 20-year-old overcame a stumble at the start to win the T44 100m final in 10.99 seconds at the IPC World Championships in Lyon.

Peacock had suffered a setback in Monday's semi-finals when Browne produced a superb 10.83 to take his world record.
