The climb
Col du Tourmalet climbs 17.1 km at an average of 7.3%, gaining 1,248 m to a summit at 2,115 m. The gradient varies through the climb rather than holding steady, so the average is a fair summary but not a description of any particular kilometre.
The hardest kilometre measures 9.6% and comes in the middle third of the climb, and 11 kilometres of the ascent average more than 8%. It does not relent at the top: the final kilometre is still 9.5%.
Above 2,000 m the air is thin enough to matter: a rider who has not been at altitude loses power over the top of a climb like this regardless of how well it has been paced. It appears on 3 stages in ProPace's data, between 2024 and 2026; each one is listed below and can be ridden in the app.
