The climb at a glance
Schematic A straight line at the average gradient – the real road is steeper in places and easier in others.
- East side from Sainte-Marie-de-Campan: 17.2 km, 1,268 m at 7.4 %, max 12 % (Wikipedia).
In the footsteps of the pros
- Tour de France: included more than any other pass, starting in 1910 (Wikipedia).
- 2023: first included in the Tour de France Femmes, as its queen stage (Wikipedia).
How long might it take?
| Sustained power | ≈ Time |
|---|---|
| 2.5 W/kg | 1 h 56 |
| 3.5 W/kg | 1 h 24 |
| 4.5 W/kg | 1 h 07 |
Estimate Physics model at constant power on a constant 7.4 % gradient: rider 75 kg, bike and kit 9 kg, rolling resistance 0.005, CdA 0.4 m², air density 1.1 kg/m³, 3 % drivetrain loss; W/kg relative to rider weight; no wind, no stops. Real times vary – this is not a standard.
Best season
High-mountain road: typically a summer and early-autumn climb – check pass opening before you travel.
Weather & altitude
Summit at 2,115 m: expect it to be much colder than in the valley – roughly 6–7 °C per 1,000 m in typical conditions.
