Usain Bolt ready to peak for London

Bolt laboured to a 10.06 seconds 100 metres victory in the Czech Republic last month and immediately travelled to see his doctor German Hans-Wilhelm Mueller- Wohlfahrt for some treatment on the back issues that have troubled him for years.

The Jamaican world record holder will test his treated back in Friday's Diamond League meeting in Monaco, which will be his last outing before he defends his 100m title and then goes in the 4x100m relay in the world championships.

"I'm feeling good," Bolt told a Monaco news conference.
