The 2013 Vuelta a Espana will be one of the hardest Grand Tours in recent history after a route containing 11 summit finishes was unveiled in Vigo on Saturday.
Organisers are keen to build on the success of the 2012 edition - which saw Team Sky's Chris Froome place fourth - when 10 summit finishes made for three thrilling weeks of racing, and have laid out a parcours that promises to be just as compelling.
A potentially decisive penultimate stage will end on the Alto de L'Angliru, which is widely regarded as one of the steepest and most challenging climbs in Western Europe, while the race will also cross over into France for the first time in a decade for an ascent to Peyragudes in the Pyrenees.
Two previously unused climbs in Andalucia have also been included, as has a trip to Andorra in an anti-clockwise circuit around Spain.
The race will feature only two time trials, with a 27km team time trial on the opening stage being followed by a 38km individual time trial on stage 11.
Team Sky notably placed two riders on the Spanish Grand Tour's podium in 2011, with Froome and Bradley Wiggins placing second and third having both worn the leader's jersey during the race.
The 2013 Vuelta runs from August 24 to September 15, starting in Vigo and ending in Madrid.
