Domestiques race in the interest of the team, or against opposing teams. By putting themselves in a breakaway they force other teams to chase. In turn, they chase a breakaway that threatens their team. Domestiques lead out sprinters by letting them 'draft' behind to conserve energy until the last few hundred meters. The lead-out train sometimes starts 10–15 km to the finish with up to eight domestiques setting a pace to discourage others from breaking away. One by one, worn-out teammates drop off. The last to lead a sprinter is often a good sprinter himself. The sprinter will launch into a dash to the line with one or two hundred meters to go. In mountainous races, domestiques help their leaders by setting a pace or thwarting attacks from others. Super-domestique There is a hierarchy among domestiques; the more accomplished, often called lieutenants or super-domestiques, are called upon during critical times. The lieutenant stays with the leader as long as possible during demanding periods. For example, Lance Armstrong used teammates Roberto Heras and José Azevedo as climbing domestiques to set pace during mountain stages of the Tour de France before making a decisive attack. Experienced super-domestiques often also have the role of captain, passing on tactical instructions to other riders and making tactical decisions when there is little or no contact with the coaching staff. Examples of traditional super-domestiques are Andreas Klöden with Astana Pro Team and George Hincapie who was a key lieutenant of U.S. Postal Team. Hincapie was also a domestique for Alberto Contador in 2007 and for Cadel Evans in 2011, when both went on to win the Tour. Recent developments in the compositions of the rosters of leading teams have led to an increasing number of high-status riders fulfilling super-domestique duties, especially during the Grand Tours. This approach was largely originated by Team Sky, beginning with their success at the 2012 Tour de France, where Chris Froome finished second on the overall podium behind his teammate and compatriot Bradley Wiggins. This finish came after some tension between the two lead riders, in particular during Stage 17 of the race, where Froome was forced to wait for Wiggins – his defined team leader – three times on the climb to the summit finish at Peyragudes, allowing Alejandro Valverde to win the stage, while both Wiggins and Froome cemented their overall general classifications standings. Following this, a number of
