Racing a motorcycle burns as much energy as a marathon

While a spectator sees a rider tucked behind a windscreen, the athlete's body is actually engaged in a violent wrestling match with physics. To navigate sharp corners at 200 miles per hour, riders like Toprak Razgatlıoğlu must hang their entire bodies off the bike, resisting gravitational forces that make their heads feel like they weigh 220 pounds. This constant bracing requires neck and shoulder muscles so overdeveloped they resemble those of elite powerlifters.
