American cyclist Tyler Hamilton retired from the sport today after testing positive for banned substances... again. Hamilton says he took steroids to alleviate his symptoms of clinical depression. I remember when Hamilton got busted the first time for blood doping--essentially transfusing someone else's blood to boost his red blood cells, and thus, his oxygen carrying ability. We had a poster of Hamilton up in our garage, crossing the finish line alone, beat to hell, but victorious, I think from the Giro or a day race, like Dauphine or Liege-Bastogne-Liege... I'm not sure. Anyway, hearts broken, we took the poster down.
