Power-walking is an official sport. It even has doping. Italian Alex Schwazer, the defending Olympic gold medalist in the 50K race walk, has been banned from the London Games after testing positive for blood doping. Olympic tests found traces of EPO, erythropoietin, which stimulates red blood cell production.
Schwazer will have to look silly working out and take intense profile shots for his website on his own time.
