So, Armstrong has announced he won't fight the USDA's doping charges against him after failing in attempts to use the courts to block the USDA investigation.

Shame for the damage he has done to the sport of cycling and the careers he has damaged along the way to this point. I imagine the reason he isn't fighting the accusations is to try to cling to what he can of his reputation because he knows the weight of evidence against him is impossible to deny now.

Edit: Excellent article on is here -
