Running is such a good exercise. It's good to lower risk of heart problems too
I believe so last i watched an athlete running and won on the tv . 
What athlete was it?
World's record athlete and i remember someone from Africa won
Ethopian Kenenisa Bekele is the fastest man in the world. 
I don't think so. The one i know is Usain Bolt from Jamaica.
Oh yeah, he's retired from running now, though
That one i agree with you.
He was  very talented, though. Defended his Olympic titles multiple times
he broke his own record like twice or three times.
