Lewis may be a lot of things, but he is by no means as fit as Jenson or Mark Webber. He's not unfit by any stretch of the imagination, but JB and MW are by far the fittest drivers.
Anyway, Anthony has cancelled whole happening with following statement:
"Unfortunately for Lewis, we are withdrawing him from this," Hamilton Snr said. "We are in the middle of a championship and that is the focus of our attention."



Fail.
Incidentally, what makes Hamilton Sr. think he knows what's best for Jr.'s championship chances? Further, how is a charity atheltic event going to impact his racing?
Gain, fail.
risk of injury! its a logical choice, post season would be the better time to do it!
Yeah, well... MS was playing soccer for charity, and it's not like you can't hurt yourself playing soccer. I think Lewis should have done it, if nothing else, then for positive publicity. He doesn't really need to kill himself while competing, just take part, worst possible scenario would be loosing to Button and giving 10000 bucks for charity.
You can have it in any colour - as long as it's black. Or red. Or blue. Or green. Or white. Or navy blue. Or...
