About the Athletics

At the moment we all following the 12th IAAF World Championships in Athletics Berlin-2009. When I thought about athletics; pentathlon , decathlon and like others are affecting me cause of being real war on athletes. Know that doing always same thing or work on the same branch is easy than others. In contrast decathlon athletes are racing at ten branches in two days.
We should accept that racing with ten branches is harder than running only 100m. Therefore what I am saying is the real athletes are doing these jobs.

Except Usain Bolt. He is doing impossible things.
Iron Man race is hardest sport. It shows your hardiness.
