Why Alpe d'Huez?
Few climbs carry the mythological weight of Alpe d'Huez. Nestled in the French Alps above the town of Bourg-d'Oisans, this road has hosted more Tour de France finishes than almost any other mountain. Every one of its 21 hairpin bends is named after a Tour stage winner. Climbing it, even on a quiet Tuesday morning, feels like riding through history.
But beyond the romance, it's also a genuinely challenging and rewarding climb — accessible enough for fit recreational riders, yet difficult enough to humble even experienced cyclists.

Breaking Down the Climb Section by Section
The Lower Slopes (Bends 21–13): The Sting at the Start
The first section is the hardest. After a short flat run out of Bourg-d'Oisans, the road rears up immediately. The lower hairpins average close to 10–11% with some ramps touching 13%. Many riders make the critical error of going too hard here. The crowds during Tour de France stages add to the excitement — and the temptation to surge. Don't. Save your legs.
The Middle Section (Bends 12–7): Finding Your Rhythm
The gradient eases slightly through the middle section, hovering around 7–9%. The road opens up, views of the valley below become spectacular, and you'll pass through small hamlets. This is where you can settle into a sustainable rhythm. Focus on cadence, breathing, and keeping your upper body relaxed.
The Upper Slopes (Bends 6–1): The Final Push
The final few kilometers before the village are mentally the most challenging. You can see the resort buildings above but the road keeps winding. The gradient here is more consistent at around 7–8%. The final straight into Alpe d'Huez village is relatively gentle — and deeply satisfying.
Practical Tips for Riding Alpe d'Huez
- Gear selection: A compact chainset (50/34) paired with a 32-tooth or larger cassette is advisable for most riders. There's no shame in spinning a low gear — it's a long way up.
- Pacing: Start conservatively. The lower hairpins feel manageable in the first five minutes; they won't feel that way if you've burned too many matches.
- Hydration: There are fountains and a small café partway up. Carry at least one full bidon from the bottom.
- Time of day: Early morning is best — less traffic, cooler temperatures, and better chance of clear views.
- Road surface: Generally good, though some patches near the lower bends can be rough. Watch for gravel on tight corners.
