About the climb

The Tourmalet from Luz-Saint-Sauveur climbs through the Hautes-Pyrénées in south-west France. It starts at 716 m and finishes at 2105 m after 18.4 km: 1393 m of climbing at 7.5% on average.

What stands out in the profile is how even it is. After an easy first kilometre, nearly every 500 m sits between 6 and 10%. There is a single short break at about 9.5 km, where the road eases to 3% for 500 m. The most sustained part comes between 12 and 15 km, at 8 to 9% almost without change, and the last 2 km still hold 8 to 9% up to the pass. The steepest 200 m on our track reaches 13.9%.

Pacing tip: a climb this regular rewards a fixed number. The calculator gives 1 h 36 min at 3.0 W/kg for a 75 kg rider and 8 kg bike; pick a power you could hold for that long and keep it there from the first ramp to the top.
