[EX Q]: Question: Which location has a higher elevation, where the sixth stage finished or where the first category of the seventh stage finish? Passage:The first five stages took place in and around Andalusia in southern Spain; the 2014 Vuelta had also started there. The first stage was a team time trial along the coast from Puerto Banús to Marbella. The next four stages were fairly flat, although Stage 2 finished on a moderately difficult climb. The sixth stage started in Córdoba and finished in Sierra de Cazorla in Jaén on another moderately difficult climb. The seventh stage then returned to Andalusia for the first major difficulty of the race: the first-category summit finish at La Alpujarra. The route then continued along the eastern coast of Spain, with a medium-mountain seventh stage and another first-category summit finish at Benitachell on Stage 9. There was one more medium-mountain stage on Stage 10, taking the riders into the Province of Castellón. This was followed by a transfer that took the riders into Andorra for a three-day spell, beginning with the first rest day. The eleventh stage took place entirely in Andorra; though it was only in length, it included six categorised climbs, including a summit finish, and was described by Eusebio Unzué (the manager of the Movistar team) as "the toughest Vuelta stage that he has seen in more than 30 years". Stage 12 took the riders back into Spain for a fairly flat stage, before three consecutive stages with summit finishes. These took place in the mountains of Cantabria and Asturias and were followed by the race's second rest day. The final week of the race included no summit finishes: the first stage was a individual time trial in Burgos and was then followed by three mixed stages that took the riders nearer to the final stage of the race, a sprint stage in Madrid. For the first time, the race organisers also held a women's race on the same day as the final stage, using the same circuit. This race – called La Madrid Challenge by La Vuelta – was won by Shelley Olds.
