Pyrenees

The Tour's favourite breather and the corridor's pastoral heart. The Aspin has been crossed 71 times, nearly always in company with its bigger neighbours, because it was the middle link of the original 1910 chain between the Peyresourde and the Tourmalet. From Arreau it climbs twelve kilometres at a civilised 6.5 percent through beech forest and open pasture, and the summit is a grass saddle where blonde cows own the road and the Pic du Midi fills the horizon head on. Nothing here will break you. It will just remind you why you came.

The Tour's newest discovery in a valley it has raced for a century. The narrow road over the Hourquette d'Ancizan only joined the race in 2011, when Laurent Mangel led over the top, and the Tour liked it so much it has returned six times in fourteen years. From Ancizan in the Aure valley it is ten kilometres at nearly eight percent, single lane in places, through hay barns and granite outcrops to a 1,564 metre notch above the Payolle plateau. Think of it as the Aspin's wild twin. Same ridge, same views, a fraction of the traffic.

The fourth most visited climb in Tour history and the first great door out of Luchon. The Peyresourde was on the founding Pyrenean stage of 1910 and the race has crossed it 69 times since, most memorably in 2016 when Chris Froome attacked over the top and tucked onto his top tube to steal yellow on the descent into Luchon. From Bagnères-de-Luchon the climb runs 14 kilometres at 6.7 percent up a classically Pyrenean staircase of meadows and hairpins. At the 1,569 metre col a small hut sells crêpes by the dozen, and the peloton itself has been known to stop.

A grand hotel on a mountaintop and seven Tour summit finishes. Superbagnères is Luchon's old rack railway resort, crowned by the vast Grand Hôtel of 1922, and its amphitheatre has staged some of the race's great theatre. Bahamontes won a mountain time trial here in 1962, Ocaña destroyed Merckx by nearly two minutes in 1971, and LeMond took yellow in 1986 as Hinault finally cracked. After 36 years away the Tour returned in 2025 and Thymen Arensman won alone. The climb runs 17 kilometres from Luchon, gentle up the Pique valley and then seriously steep through the upper hairpins to the plateau.

The best balcony in the corridor and the launchpad of a dynasty. The Col d'Azet rises out of Génos in a stack of steep hairpins above the Louron lake, seven and a half kilometres at 8.3 percent with barely a metre of respite, and every switchback opens the valley a little wider below. At Val Louron beneath it in 1991, Claudio Chiappucci won the stage and Miguel Indurain pulled on the first yellow jersey of an era that lasted five Tours. The race has been back roughly ten times since 1997, most recently in 2022. Ride it late in the day, when the light comes up the valley and the lake turns to metal.

The roof of the Pyrenean Tour. When the race paved and climbed the Col de Portet in 2018 it created its highest summit finish in the Pyrenees at 2,215 metres, a hundred metres above the Tourmalet, and Nairo Quintana won the debut. Pogačar's 2021 masterclass confirmed it as the range's new judge. From Saint-Lary-Soulan it is sixteen kilometres at 8.7 percent, the hardest climb in the Hautes-Pyrénées by climbfinder's maths. It shares its opening ramps with Pla d'Adet, then breaks away at Espiaube onto a single lane road through a bare upper bowl where the tarmac seems to end at the sky.

Only Alpe d'Huez and the Puy de Dôme have hosted more summit finishes. The ski balcony above Saint-Lary has decided eleven Tours since 1974, when a 38 year old Raymond Poulidor won the inaugural finish ahead of Merckx, and the habit never faded. Pogačar won here again in 2024. The climb is ten and a half kilometres at eight percent with a first act that means business immediately, hairpins stacked at ten percent straight out of Saint-Lary. It shares those opening slopes with the Col de Portet, then branches at Espiaube for the terrace and its view over the whole Aure valley.

The late addition the evidence demanded. Hautacam rises above Argelès-Gazost at the western gate of Tourmalet country, and no climb of its size carries more modern Tour weight. Six summit finishes since 1994, when Luc Leblanc won the first in the rain, and in 2022 Vingegaard broke Pogačar here to all but win the Tour. The road itself is a shape shifter, 15 kilometres at 7.9 percent on paper but almost never actually 7.9 percent, lurching between ten percent ramps and false flats through a scatter of hamlets with the Lavedan valley and the sanctuaries of Lourdes falling away below.
