Most professional cyclists spend their entire careers sacrificing their ambitions while helping others attain theirs. The cycling world refers to these riders as domestiques, which means "servants" in French. They place themselves in service of their team leader. Domestiques' responsibilities include falling back to the team car to grab water bottles and food for their team leader, protecting their leader from the wind by allowing him to ride in their slipstream (saving him about 30% of his energy by drafting), and giving their bike or wheel to their team leader if he has a mechanical issue. Domestiques rarely win a professional race throughout their career.  But something unusual happened in this year’s edition of the Tour de France, the world's most demanding endurance race.[1]
