Martin won the 10-mile time trial in 20 minutes, 53 seconds to claim the title with an overall time of 18 hours, 48 minutes, 45 seconds.

Contador placed 15th in the final stage and finished fourth overall, 41 seconds behind Martin.

"The time trial did not come out quite right, but to be here is already a triumph," three time Tour de France champion Alberto Contador commented and added "I think I had a good performance for the first race. I've read in a newspaper that I had gone 205 days without racing, and that is too long."

Contador tested positive for the banned substance clenbuterol in last year's Tour de France. The Spanish cycling federation initially had proposed a one-year ban before accepting his claim that he unintentionally ate contaminated meat.
