September 26 Usain Bolt is warning the rest of the world that they should be very worried, now that he and teammate Yohan Blake are major competitors. In an interview with ESPN, while in Europe; Bolt who was reflecting on the false start in the 100 metres in Daegu said “It won’t happen again. “

“Yohan and I are training partners, friends and we still joke around, but London 2012 is going to be very interesting. I want to defend my titles and he wants to compete at the highest level – that makes the competition interesting,” warned Bolt.

Bolt ended the season with a world leading 9.76 seconds over the 100 metres in Brussels after leaving Daegu with one less gold medal than expected. He won the 200 metres in 19.40 seconds and anchored the Jamaican 4 X 100 metres relay team to 37.04 seconds. The team was responsible for the only world record to the run at the Championship.
