MADRID — Chris Froome finished Spain’s Ruta del Sol race in 10th place behind winner Tim Wellens on Sunday.

The five-stage race in southern Spain was Froome’s first event since the four-time Tour de France winner was found to have failed a doping test at last year’s Spanish Vuelta.

Froome, who denies any wrongdoing, has been ordered to explain to the International Cycling Union why a urine sample he provided at the Spanish Vuelta in September showed a concentration of the asthma drug salbutamol at twice the permitted level.

Wellens, a Belgian rider for Lotto-Soudal, defended his lead over the final day’s time trial.

Wout Poels, of Froome’s Sky Team, was second at eight seconds behind.

Froome, who won the event in 2015, finished 1 minute, 57 seconds behind. He started the time trial on the final day in 14th after a puncture toward the end of Saturday’s fourth stage.
