Okay - I'm admittedly late to the tennis match on this one but I couldn't deny you Rafael Nadal playing with balls, could I?
The Majorcan Matador joins other Olympic athletes including Michael Phelps, Asafa Powell, Barbora Spotakova, Lindsey Vonn and Pernilla Wiberg for a user-generated contest called "The Best of Us Challenge."
It gives fans an unique opportunity to compete against their fave athlete by breaking the sports star's record in a Challenge they created themselves. Anyone who records and submits their Challenge is eligible to win a trip to the Vancouver 2010 Winter Olympic Games or the first-ever Youth Olympic Games in Singapore. In addition, those who beat or come closest to beating their Olympic athlete are eligible to win Gold, Silver, and Bronze level prizes.
So, can you beat Rafa at his Challenge (read: are your thighs strong enough to crack walnuts?)
