Britain's Geraint Thomas is set to win the Tour de France after maintaining his overall lead on the penultimate stage of the race, a 31km time trial.

The Team Sky rider, 32, finished third behind Tom Dumoulin but still leads the Dutchman by one minute, 51 seconds.

Tour convention dictates that the race leader is never challenged on the final stage, so Thomas only needs to reach the finish in Paris on Sunday to win.
