LARUNS, France — Having worn the leader’s yellow jersey over the Alps and through the Pyrenees, only one more challenging stage stands in the way of Geraint Thomas winning his first Tour de France.

Thomas takes an advantage of 2 minutes, 5 seconds over Dutch rival Tom Dumoulin into Saturday’s 31-kilometer (19-mile) individual time trial in the Basque Country.

The pressure of leading has reminded Thomas of the time he helped Britain to the gold medal in team pursuit on the track at the 2012 London Olympics.

“It comes down to tomorrow,” he said.
