Froome: The Vuelta is a race I love but it's relentless

Chris Froome has described the Vuelta a España as 'unfinished business' as he tries to transform his run of second places into a first victory and become only the third rider to complete the Tour de France-Vuelta double. Froome has purposely built his season around going for the double but admits that completing the job after winning a fourth Tour is the hardest part of the challenge. Yet he insists it is also that is the most motivating part.
