Alpe d’Huez, a cycling icon

Alpe d’Huez is one of the most iconic mountains in cycling and thousands of people visit every year to cycle the 21 hairpin bends that makes it famous. The climb to Alpe d’Huez starts in the town of Borg d’ Oisans and covers 13.2km at an average gradient of 8.11% before reaching the summit at 1,815m. It was first used in the Tour de France in 1952 and has been used 30 times in total. In the 2013 Tour de France, it was climbed twice with riders descending via Col de Sarenne before heading up again to finish at the top. In the winter months, Alpe d’Huez is a ski resort attracting skiers instead of cyclists.

No cycling holiday to France is complete without tackling this famous climb. This cycling route is a simple out and back from Borg d’Oisans to the top and back down. There are cafes and restaurants at the top of the climb to enjoy and provide some refreshments before you head back down. Make sure you stop periodically on the way back down to enjoy the view and marvel at what you have achieved.

We climbed Alpe d’Huez the day before the Tour de France tackled the climb twice in 2013. There were already thousands of fans on the side of the road getting their position for the race the next day. It created a fantastic atmosphere for the ride and there were lots of cheers and encouragement as we climbed. If you get a chance to be there in a year the Tour de France will ride Alpe d’Huez we highly recommend riding it the day before the race.

We have plenty more cycling routes in the French Alps for you to try out while you visit.

Gradient profile of Alpe d'Huez

Steep From the Outset

From Bourg d’Oisans the climb is situated just a short distance from the center of town. If you want a bigger warm-up before taking the climb on, perhaps ride down the valley a little further. The gradient is at its steepest for the first two hairpin bends where the average hovers between 10 and 11% with no relief. Try to stay within yourself here and save your energy for later in the climb.

Counting down 21 bends

Unlike other famous climbs which have signs up for every passing kilometer, Alpe d’Huez helps you measure progress as you pass each bend in the road. There are 21 all up and each has a number and a plaque to feature a previous tour stage winner. They can be a great distraction as you make your way up the mountain. The hairpin bends also provide temporary relief in the gradient. Typically the climb flattens off as you turn each bend so depending on how you feel, you can either click up through the gears and lift the pace or use each bend as a point where you can spin the legs and enjoy some rest.

Dutch Corner

Other landmarks to tick off along the climb includes the small village of Huez as well as the famous Dutch Corner. Alpe d’Huez is also known as the ‘Dutch Mountain’ due to the number of Dutch riders who have previously won a stage on this climb. As the road makes it’s way ever higher you will enjoy views out across the valley. The road is really cut in tight on the mountainside so you don’t actually get many views of the road itself.

Two Summits

You will reach the top of the official climb once you arrive at Vieil Alpe. Continue on for a further kilometer and you will reach the official summit which the Tour de France uses. Once recovered enjoy the magic descent all the way back to Bourg d’Oisans.

Food and water

Top up with food and water for the climb before you leave Bourg d’Oisans.

There are plenty of places to stop and refuel at the top of the climb.
