Pla d'Adet
Pla d'Adet front-loads its difficulty: the first 5 km out of Saint-Lary hover around 10%, hairpin after hairpin cut into the cliff, before the angle finally relents towards the ski village. Pacing the opening is everything.
Summit elevation: 1680 m

Pla d'Adet and the Tour
A Tour summit finish since 1974, when Raymond Poulidor won the inaugural stage here at age 38. The climb anchored many classic Pyrenean stages of the 1970s-90s.
The 2024 Tour returned to Pla d'Adet, with Tadej Pogačar winning the stage. Its steep first half consistently produces bigger time gaps than its modest length suggests.

When to go
Rideable May to October. The lower cliff section is south-east facing and hot by mid-morning in summer — it is a climb best started early.
Base & logistics
Saint-Lary-Soulan at the base has full services and a cable car if the descent doesn't appeal. Combine with the Col de Portet (shared lower ramps) or the nearby Hourquette d'Ancizan-Aspin circuit.
FAQ
How long is the Pla d'Adet climb?
From Saint-Lary-Soulan, the climb is about 9.8 km with roughly 851 m of elevation gain at 8.7% average gradient (based on the simplified profile used by this simulator; published figures vary slightly by source).
How long does it take to cycle up Pla d'Adet?
It depends almost entirely on your power-to-weight ratio. Use the simulator on this page: enter your FTP and weight, and a physics model (air resistance, rolling resistance, gravity) estimates your time on the gradient profile.
How accurate is the time simulation?
The simulator uses a simplified segment profile and standard road bike assumptions (CdA 0.32, Crr 0.004, 8 kg bike). It does not model wind, drafting, altitude, surface or pacing errors, so treat the result as a realistic estimate, not a guarantee.
How should I train for Pla d'Adet?
Sustained climbs reward steady threshold and sweet spot work plus a power-to-weight improvement over weeks, not days. TrainCraft builds structured cycling training plans and adapts them when you miss sessions, using fatigue science (CTL/ATL/TSB).
