Stage 20 of the 2026 Tour de France begins unusually early, with the riders facing 170.9km and 5,450 metres of climbing from Le Bourg-d’Oisans to Alpe d’Huez on Saturday 25 July.
UK live coverage begins at 10:00 BST, only 20 minutes before the neutralised start. Racing is expected to begin at approximately 10:30 BST, with the finish scheduled between 15:11 and 15:50 BST.
This is not a stage where viewers can safely wait for the final climb.
The Col de la Croix de Fer begins almost immediately, while the Col du Télégraphe and Col du Galibier form an enormous climbing block through the middle of the day. The Col de Sarenne is the final categorised climb before the descent and approach to Alpe d’Huez.

The wide finish window reflects the difficulty of predicting the speed of a stage containing four major climbs and more than 5,000 metres of elevation gain.
The full sporting picture is covered in our Tour de France 2026 stage 20 preview.

There is no long flat introduction. The race heads towards the Col de la Croix de Fer immediately, so attacks should begin soon after the flag drops.

The best time to tune in depends on how much of the race you can watch.
Watch from 10:00 BST for the full breakaway battle
Coverage begins shortly before the neutralised start.
The riders begin climbing almost immediately, so the fight to enter the breakaway should develop on the road towards the Croix de Fer.
This opening phase also matters for the mountains classification. Richard Carapaz, Tadej Pogačar and Valentin Paret-Peintre are separated by only seven points before the stage, with 20 available at the first summit.
Carapaz and Paret-Peintre may need to attack from the opening kilometres rather than wait for the Galibier.
Watch from 12:45 BST for the Télégraphe and Galibier
Viewers joining at approximately 12:45 BST should see the closing section of the Col du Télégraphe and almost all of the Galibier ascent.
The Télégraphe summit is expected between 12:56 and 13:17 BST. After a short descent through Valloire, the riders begin the 17.7km climb to the Col du Galibier.
The Galibier summit is scheduled between 13:43 and 14:11 BST.
This is the best option for anyone who wants to see the important general classification racing without watching the complete stage.
Paul Seixas needs 25 seconds to take third overall and the white jersey from Isaac del Toro. The upper Galibier provides the first obvious place for Decathlon CMA CGM to launch a long-range move.
The latest positions are covered in GC and jerseys after Tour de France 2026 stage 19.
Watch from 14:30 BST for the decisive finale
Anyone restricted to the final hour should tune in by 14:30 BST.
The riders should be approaching Mizoën and the lower part of the Col de Sarenne. The breakaway’s advantage, the state of the GC group and the shape of the polka-dot jersey contest should all be clear by this point.
Sarenne is expected to be crested between 14:51 and 15:28 BST. Only 14.4km remain from the summit, including the descent and final approach through Alpe d’Huez.
The earliest finish is scheduled for 15:11 BST, so waiting until 15:00 could mean missing the decisive attack.
Stage 20 key viewing schedule
| UK time | What should be happening |
|---|---|
| 10:00 | Live coverage begins |
| 10:20 | Neutralised start |
| Around 10:30 | Racing begins |
| 11:38–11:49 | Col de la Croix de Fer summit |
| 12:16–12:30 | Intermediate sprint |
| 12:56–13:17 | Col du Télégraphe summit |
| 13:43–14:11 | Col du Galibier summit |
| 14:22–14:53 | Race approaches the Col de Sarenne |
| 14:51–15:28 | Col de Sarenne summit |
| 15:11–15:50 | Stage finish at Alpe d’Huez |
All passage times are estimates rather than fixed appointments.
A very aggressive opening could move the stage towards the earliest schedule. A slower race or prolonged tactical battle could place events towards the later end of each window.
Why does stage 20 begin so early?
Stage 20 starts earlier than most days because it is the hardest mountain stage of the 2026 Tour.
The route contains:
- 170.9km of racing
- 5,450 metres of climbing
- Three hors catégorie climbs
- One category one climb
- The Tour’s highest point on the Col du Galibier
- A technical descent after the final summit
A later start would push the finish too far into the afternoon, particularly if the peloton follows the slowest projected schedule.
The stage’s scale and importance are examined in our Tour de France 2026 queen stage guide.
What should viewers watch for on the Croix de Fer?
The Col de la Croix de Fer reaches its summit after only 33.7km.
It measures 24km at an average of 5.2%, although its changing gradients make it more difficult than that figure suggests.
The main opening stories should be:
- Carapaz and Paret-Peintre attempting to enter the breakaway
- Teams without a stage victory sending climbers ahead
- Bahrain Victorious deciding whether Lenny Martinez can attack
- Lidl-Trek placing a rider in front to support Mattias Skjelmose
- Decathlon creating a possible satellite option for Seixas
The summit is expected between 11:38 and 11:49 BST.
If a powerful group containing high-placed riders forms here, the stage may become difficult to control before midday.
The Galibier could begin the podium battle
The Col du Télégraphe and Col du Galibier combine to create almost 30km of connected climbing.
The riders briefly descend into Valloire after the Télégraphe, but there is not enough time to recover fully before the Galibier begins.
The Galibier reaches 2,642 metres and comes with 60.4km remaining. Its summit is expected between 13:43 and 14:11 BST.
This is where Seixas, Skjelmose or Juan Ayuso could attempt a long-range attack.
Seixas begins the day only 24 seconds behind Del Toro in the battle for third and white. Waiting until the closing kilometres of Sarenne would reduce the number of opportunities available to create that gap.
Remco Evenepoel must also decide whether to attack or protect second place. He trails Pogačar by 7:11 but has only 2:31 over Del Toro.
The climb’s wider significance is covered in our history of the Col du Galibier at the Tour de France.
Sarenne replaces the traditional Alpe d’Huez ascent
Stage 20 finishes at Alpe d’Huez, but the riders will not repeat the traditional climb through the 21 hairpins.
Instead, the route approaches from Mizoën and climbs the Col de Sarenne from its south-eastern side.
Sarenne measures 12.8km at 7.3% and reaches its summit at 1,999 metres. From there, the riders descend towards Alpe d’Huez before completing the approach through the resort.
The summit should arrive between 14:51 and 15:28 BST.
There are 20 mountains points available on Sarenne, making it the final scoring opportunity in the polka-dot jersey battle. No additional mountains points are awarded at the finish.
The difference between the two final Alpine stages is explained in why the back-to-back Alpe d’Huez finishes could define the Tour de France 2026.
What time will Pogačar finish stage 20?
Pogačar and the other main general classification riders are expected to reach the finish between 15:11 and 15:50 BST.
The precise time will depend on the speed of the opening kilometres and how aggressively the race is ridden across the Croix de Fer.
The fastest official projection produces a finish at 15:11 BST. The middle schedule gives a finish at approximately 15:29, while the slowest projection reaches Alpe d’Huez at 15:50.
A fast opening followed by more tactical racing could produce a finishing time anywhere between those estimates.
Being in front of the television by 14:30 BST is the safest option.

Tour de France stage 20 viewing recommendation
Stage 20 is worth watching from the start.
The early Croix de Fer should produce an extended breakaway battle and could decide whether Carapaz or Paret-Peintre controls the mountains classification. The Galibier gives Seixas and Lidl-Trek terrain for a long-range GC move, while Sarenne provides the final test before Paris.
The essential UK timings are:
- 10:00 BST: live coverage begins
- 10:20 BST: neutralised start
- Around 10:30 BST: racing begins
- 13:43–14:11 BST: Galibier summit
- 14:51–15:28 BST: Sarenne summit
- 15:11–15:50 BST: expected finish
Anyone joining for the final hour should be watching by 14:30 BST.
Anyone wanting to understand how the stage develops should be there from 10:00 BST, because the race may begin taking shape before the morning is over.
