This will be one of the most interesting event to watch out for in the coming London Olympics, besides than the opening and closing ceremonies; the athletics men 100 meters. In the previous edition, we saw how Usain Bolt created the world records in the 3 events he participated.
This time around, there seems to be a new challenger for Bolt. His name is Yohan Blake, also from Jamaica. He managed to beat Bolt in the 100 meters at the recent Jamaican Olympic trials where he clocked 9.75 seconds to Bolt's 9.86 seconds. Yohan also beat Bolt in the 200 meters in the same trials, 19.80 seconds to Bolt's 19.83 seconds. But this was far off from Bolt's 2008 world record of 19.19 seconds.
Anyway, I think there is no reason to worry for Bolt. I believe in him peaking at the right time. He will definitely win, and could possibly with another few world records. We saw from 2008 that he slowed down towards the finishing line because there is no one to push him run harder. This was a natural human reaction. With Yohan by his side, Bolt will surely bolt further, faster and greater.
