Profile stage 20 Tour de France 2025

There are no more flat stages in the Tour de France. After the Alps, there is no time to rest, because in addition to the ride to Paris—where the climb to Montmartre could disrupt the sprinters' party—the 20th stage is really tough. From Nantua, the riders begin a challenging hill climb alongside a beautiful lake.
The climbing starts almost immediately. From Saint-Germain-de-Joux, the Col de la Croix de la Serra begins. It is long but not steep (12.1 kilometers at 4.1%). After the descent, it immediately goes uphill again: the Côte de Valfin is slightly less difficult, but the road continues to climb for quite some time after the top. The first 50 kilometers could therefore be a significant battle for the day's breakaway.

Lenny Martinez is the last winner in Pontarlier, at the Tour du Doubs.
We continue north: on the plateau after the second climb, there is an intermediate sprint in La Chaux-du-Dombier. The battle for the green jersey seems to be decided, so we don't expect a fierce sprint there. Then it's a long, winding road downhill to Salins-des-Bains. However, the most challenging climb of the day lies ahead.
It's not long, but at 4.5 kilometers and an average gradient of 9%, the Côte de Thésy is a tough climb. The top of this climb is more than 60 kilometers from the finish line: don't expect a solo breakaway from this point, but the race could well explode here.
By now, the route has turned eastward, approaching Pontarlier. It is never flat: the road continues to go up and down. The Côte de Longeville is the last categorized climb (2.6 kilometers at 6%), but there are still some difficult sections after that. Once in the finish town, the riders will have almost 3,000 meters of elevation gain in their legs. It will be a grueling day, where the breakaway riders will have to give their all to get a chance to succeed.

Weather stage 20 Tour de France 2025
No dry start in Nantua. It won't be too hot in the foothills of the Alps, and there will also be some rain. As the day progresses and the race moves north, thunderstorms are also expected to develop. The precipitation will increase, and in Pontarlier, it will not be 17 degrees with heavy rain. We do not expect any echelons: the gentle wind will mainly be noticeable when it blows directly into your face.
Favorites stage 20 Tour de France 2025
We do not expect a battle for the GC, and the sprinters will have a tough time. It will be the attackers, the men with the big engines, who we will see at the front in the penultimate stage. It seems tailor-made for Wout van Aert. The Belgian from Visma | Lease a Bike, perhaps with teammates Tiesj Benoot and Victor Campenaerts, could help his team to a second stage win in the Tour, after Simon Yates' success on Mont Dore.
But the competition is intense. Among the Belgians, we have to keep an eye on Thibau Nys: the Lidl-Trek rider was not at his best in the first week of the Tour, but on the way to Carcassonne, he suddenly showed his true potential. The winner last time was Tim Wellens, but riders such as Jasper Stuyven and Gianni Vermeersch also have a chance in a stage like this.
Are there other (Dutch) riders we should write down? Honestly, apart from Pascal Eenkhoorn (Soudal Quick-Step), Thymen Arensman (INEOS Grenadiers), and Frank van den Broek (Picnic PostNL), we don't see anyone who could shine today. With powerhouses like Jonas Abrahamsen (Uno-X Mobility), Iván Romeo (Movistar), Mauro Schmid (Jayco-AlUla), and Axel Laurance (INEOS Grenadiers), the rest of the pack seems to be lacking the necessary power.

The French will be eagerly anticipating the route. What can we expect from Julian Alaphilippe (Tudor) and Romain Grégoire (Groupama-FDJ)? This pair is made for unpredictable stages like this. Riders such as Valentin Madouas, Aurelièn Paret-Peintre, and Louis Barré also have a chance of winning. Alaphilippe can also count on Marc Hirschi at his side.
But the team with the most strength across the board is perhaps EF Education-EasyPost. Normally, we would pick Ben Healy, but after his ambitions in the GC, we are also considering guys like Vincenzo Albanese, Kasper Asgreen, Alex Baudin, Neilson Powless, and Harry Sweeny. What a luxury... Bahrain Victorious can also count on several key riders, including Matej Mohoric and Fred Wright.
We mustn't forget Quinn Simmons either. Teammates Nys and Stuyven have already been mentioned, but the American champion, like Latvian champion Toms Skujins, is very comfortable on this terrain. Captain America will be up for it, you can write that down! Other contenders: Simone Velasco (XDS-Astana), Joe Blackmore (Israel - Premier Tech), and Jhonatan Narváez (UAE Team Emirates - XRG).
Or will Tadej Pogacar try something? It is possible that several riders in the top ten will attack each other and that it will be a very fierce day in the Jura, as we have seen in the past in the penultimate stages of the Vuelta a España. It is possible that riders such as Ben O'Connor (Jayco AlUla) and Kévin Vauquelin (Arkéa - B&B Hotels) may also still have ambitions.
Who are the favorites for stage 20 of the 2025 Tour de France, according to IDLProCycling.com?
Top favorites: Quinn Simmons (Lidl-Trek) and Wout van Aert (Visma | Lease a Bike)
Outsiders: Jhonatan Narváez (UAE Emirates-XRG), Ben O'Connor (Jayco AlUla), Victor Campenaerts (Visma | Lease a Bike) and Julian Alaphilippe (Tudor)

- I’m still learning the calendar: is cyclocross mainly preparation for the spring classics, or does he race it as a separate goal as well? I’d love to see him back in the mud.jeremya04-11-2026
- The article makes it sound as if Roubaix is the only classic where he has a realistic shot. He’s been close in Flanders too, and one good tactical day can change everything.jennifer1904-11-2026
- Milan-Sanremo and Roubaix is a pretty special pair of Monuments. Any clues yet on which cyclocross races he’ll target?andrewf04-11-2026
- He’s right to be realistic about Flanders with Pogačar and Evenepoel around, but you can’t count Van Aert out on those roads. If he gets the right opportunity, he has the engine and experience to take it.davidm04-11-2026
- That Roubaix win felt like such a release after all the near-misses. Brilliant to hear that joy outweighed relief for Wout.patriciaw04-11-2026
- Why would a mountain time trial be different from a normal one? Is it just that the riders have to climb the whole course?samanthak03-11-2026
- I don’t quite buy the “fear of failure” argument. Riders can race the Giro and still have confidence in July; it comes down to recovery and planning, doesn’t it?patriciaw03-11-2026
- The Giro-Tour double is a massive ask, even for the very best. Pogačar made it look almost routine in 2024, but that’s hardly a sensible benchmark for everyone else!pedalpowe2903-11-2026
- Bakelants makes a fair point: if the 2027 Tour really suits Remco, he can’t afford to dilute the build-up. That 37km flat TT will be tempting, mind.julien03-11-2026
- Mont Blanc sounds like a spectacular finish, though four climbs on the final day might be a bit much after eight hard stages. Hope the route details are clear soon.raceready703-11-2026
