Remco Evenepoel has been wearing a gold helmet for most of this year's Tour as he won the gold medals in both the time trial and road race events at last year's Paris Olympics.

The Belgian's also wearing a rainbow jersey for the time trial as he became world champion in Zurich last September.

The 25-year-old won the other time trial of this year's Tour, finishing 16 seconds ahead of Tadej Pogacar on stage five, so is sure to be targeting another win today.

An individual time trial takes the riders from the valley floor up to the runway of Altiport 007 in Peyragudes.

After a flat start, there will be more than 8km of uphill and no hiding place for the GC favourites in the race of truth.

A gradient of 7.8% ramps up to a punishing 13% in the final kilometre, with the temperature again set to hit 33C.

The Tour arrived in the south of France for Tuesday's stage in Toulouse.

Then the riders headed into the Pyrenees for the first true mountain stage of this year's Tour.

Now we're set for a time trial which ends with a punishing climb on the Peyragudes mountain rescue airfield, giving Tadej Pogacar's rivals an immediate opportunity to cut the gap after he regained the yellow jersey yesterday.

Tadej Pogacar regained the overall lead of the Tour de France as he stormed up the Hautacam climb to win stage 12.

Jonas Vingegaard's Visma-Lease a Bike team were expected to attack the reigning champion on the first true mountain stage of this year's Tour, which ended with the first summit finish.

Pogacar was also sporting dressings on his left arm after falling at the end of Wednesday's stage, but the Slovenian showed no ill effects as he attacked on the gruelling final climb.

The three-time Tour winner went clear early on the 13.5km ascent and continued to stretch his lead, winning the stage by two minutes 10 seconds from Vingegaard - his biggest margin of victory on a Tour stage.

That meant he reclaimed the yellow jersey from Ireland's Ben Healy as the breakaway specialist lost more than 13 minutes and Pogacar more than doubled his time advantage over Vingegaard, his main general classification rival, who is now 3 mins 31 secs behind.
