Alberto Contador's route to the Vuelta a España will take him via the Clasica San Sebastian and the Vuelta a Burgos

Alberto Contador has confirmed that he will return to cycling at the Clasica San Sebastian on July 30 in a build up to riding the Vuelta a España in August and September.

The Spaniard abandoned the Tour de France on stage nine after crashing twice in the first week and struggling with the pace, ruling him out of the Olympic Games as well.

Instead, Contador will attempt to win his fourth Vuelta title and will get there via San Sebastian and the Vuelta a Burgos between August 2-8.

Another general classification heavyweight that may decide to ride the three-week race after the Olympics is Nairo Quintana, who has looked out of sorts at the Tour de France so far.

The Colombian has failed to mount any kind of challenge to Chris Froome over the Tour’s first 17 stages and could look to the Spanish Grand Tour to provide a late boost to his season.
