What you should know
- Route tackles Glandon, Télégraphe, Galibier (2645m) and Alpe d'Huez — pace conservatively on the opening climb.
- Glandon descent is traditionally neutralized; follow marshals as timing is paused and racing it gets you removed.
- Expect cold air and wind at Galibier summit even on sunny days — pack a shell for the long descent.
- Strict time cutoffs apply at intermediate checkpoints; missing one means course removal by the broom wagon.
- Feed stations sit ~30-40km apart; carry your own fuel and top up bottles at every stop in the heat.
