🏆 71 Tour appearances since 1910 A first-Pyrenean-stage original. In 1950 spectators pelted the riders with bottles and stones here and the Italian team — Bartali included — quit the race in protest. The bar is low; just keep pedalling.
Starts from the front door, which neatly removes your last excuse. Gentle for 2km, then a steady 5–8% staircase with six hairpins. Worth remembering: this is the easy one.

🏆 ≈90 crossings — the most of any climb in Tour history First crossed in 1910, when Octave Lapize pushed his bike over the top and called the organisers assassins. In 1913 Eugène Christophe snapped his fork on the descent and forged a new one himself in Sainte-Marie-de-Campan. Pogačar soloed over it to take yellow in this year's Tour.
18km at a metronomic 7–8%, exactly one merciful kilometre at Barèges, then a 9% ramp to finish. No tactics, no clever line, nowhere to hide — just you, your gearing choices, and the consequences of both.

🏆 6 Tour appearances — all since 2011 One of the Tour's newest Pyrenean roads: it didn't debut until 2011, mostly because nobody had bothered to surface it properly before. Quiet, beautiful, full of marmots.
14km of false flat during which you'll assure everyone you've recovered from the Tourmalet, then a 6–8% reminder that you have not. Features a cheeky mid-climb descent — a gift or a taunt, depending entirely on how your day has gone.

🏆 0 Tour appearances — ever The only climb of the weekend the Tour has never touched, for the excellent reason that the road ends at a 100m-high dam holding back the biggest reservoir in the Pyrenees. No through road, no race. We're doing it anyway — it's higher than the Tourmalet, and if it's hot, lunch and a swim at the top.
Seven gentle valley kilometres to lull you into confidence, then a 10km core at 7–9% up to a glacial lake at 2,161m. A brutally serious climb dressed as a nice day out. Bring trunks; earn the swim.

🏆 2 Tour appearances — both summit finishes The Tour's newest monster: Quintana won its 2018 debut (the day Froome cracked), Pogačar won there in yellow in 2021. PJAMM rates it the second-hardest road climb in France — harder than the Tourmalet.
Opens at 10% and sees no particular reason to stop. One flat half-kilometre at the Espiaube hairpin — wave at it as it goes past — then relentless to 2,215m, the roof of the trip. Scheduled, with love, for the day after the Tourmalet.

🏆 ≈70+ crossings since 1910 Part of the very first Pyrenean stage in 1910 — the Luchon–Bayonne 'Circle of Death'. In 2016 Chris Froome attacked over the top and descended into Luchon sitting on his top tube like a lunatic. Please don't.
Ten kilometres of cheerful chatting up the Louron valley, then seven kilometres of conspicuous silence at a sustained 7–8%. There is a crêpe shack at the summit. This is not a rumour, it is the entire plan.

🏆 7 Tour summit finishes The stage where LeMond beat Hinault in their famous 1986 civil war, and where Robert Millar won in 1989. Back in the Tour in 2025 after 36 years (Arensman won, Pogačar in yellow). The gradient labels on the hotel switchbacks are printed on the road.
Irregular and sneaky — breathers at km 4 and 8 that lure you into spending matches, then an 8% run from km 11 and a 9% finish to the ski station. The views at the top are the second-best reward. The first is stopping.

🏆 10 Tour appearances since 1997 Marco Pantani led over it on its 1997 debut. Next door is Val Louron, where Indurain took the first yellow jersey of his five-Tour reign in 1991. Short climb, long list of victims.
7.4km at 8.3%, as the final climb of the final day, with the first 4km all at 8–10%. Yes, it was put there on purpose. Complaints may be submitted to the management in writing, from the top.
