Ah yes, Alpe d’Huez…
What could I possibly add to the many, many pages dedicated to this particular climb, one that’s on the bucket list of nearly every cyclist who dares to venture into the Alps?
A climb that is imprinted into the memory of Tour de France followers as being ‘pivotal’ in many a stage, if not decisive to the overall win.
Which, at the time of posting this page and looking at the ‘hard evidence’, has only been the case in 7 out of the 29 times the Alpe has been included in the TDF…
On 6 more occasions, the yellow jersey switched shoulders after the stage, but the TDF was eventually won by another rider.
Only Greg Lemond and Stephen Roche were able to turn the table again: after losing the yellow on the Alpe, they eventually still won the GC.
Despite it’s fame, it’s not even the highest or the hardest climbs in the area and it’s not particularly beautiful.
Dutch Corner and Alpe d’HuZes
Of course, from a Dutch point of view, the Alpe is special.
After all, there were 8 stage winners from ‘les Pays-Bas’, which – at the time of the last win – was more than half of the stages that included the Alpe.
And even if it has been a while (1989), the Dutch fans still claim bend 7 as their very own ‘Dutch Corner‘, coloring it orange during race days…
However, there is probably nothing like the Dutch taking over the entire Alpe and Bourg d’Oissans during the fundraiser event called ‘Alpe d’HuZes‘, when it becomes the epitome of their fight against cancer.
You can read more on that on my ‘Alpe d’HuZes‘ page, but during the year of our Team AD6 Tweets’ participation, I climbed the Alpe eight times in total within less than a month, seven of which within a week, so I have come to know it quite well.
Or, at least the classic route of it – I also once rode the very nice ‘Villard-Reculas’ version, but never the ‘Col de Sarenne’; both of these alternatives are described further on.
And during my Marmotte of 2021, I ascended (the classic route of) the Alpe d’Huez for the 10th time 🥳.
(And for the 11th time in the Epilogue of my Tour de France 2022)
Since June 2011, there’s a Bend 0 sign on Alpe d’Huez, which is located in the final hairpin after entering Alpe d’Huez and going through the tunnel.
It’s named after Bas Mulder from Harderwijk, who died of lymphoma in September 2010 and who was one of the inspiring icons of Alpe d’HuZes.
Filmmakers Ariane Greep and Bas Steman followed him during the last four years of his life and made the documentary “Alpe d’HuZes: The Final Bend” (Vimeo, in Dutch).
The Classic Route
From Bourg-d’Oisans, this climb is 13.8 kilometers long, navigating 21 hairpin bends along the way and this is the route the TDF takes.
Each of the hairpins is labeled and named after a former stage winner.
As there have been more stage winners than there are bends, they started adding names from the bottom (#21) up again, so a couple of signs have two names on them.
The ‘official’ start is at the camping La Cascade – from that point, the climb is 13.4 kilometers, with an elevation gain of 1,129 meters.
Perhaps you’re not easily scared by that 8.4% average, but if you base your effort on it and perhaps start out a little overconfident during the first two kilometers, you’ll be regretting it and cursing yourself later.
And if it’s hot down in the valley – and temperatures well over 35 degrees are not an exception on a summer’s day – you probably should take it down a couple of notches anyway, especially during the first tough kilometers.
In fact, if you have a choice, it would be best to avoid those conditions altogether and pick an early start for your climb…
While the first couple of kilometers, with an average of over 10%, are listed as the toughest, there are several equally tough stretches later on.
These include both stretches before entering La Garde and Huez, and the part between bends 3 and 2.
The first time I climbed up – half past dead from injuries and the preceding Croix de Fer – I particularly developed an aversion against the part between bends 7 and 6.
I’m not sure why, but I know it hasn’t faded away during my later ascends…
All (but one) hairpins are relatively flat if you ride the outside curve, so you could use that to your advantage.
This may well contribute to the reason why the overall average of this climb is what it is – moderately hard – because most stretches in between are over 9%.
And remember, there probably are professional photographers along the route to capture your effort. These are typically stationed in the upper hairpins, like number 5 (sometimes) and number 2 (nearly always).

Note that both profile cards – the classic above and the Villard-Reculas alternative below – read ‘Col du Poutran’ as finish.
From Alpe d’Huez, this is another 4 kilometer, named ‘Route des Lacs’, with a gravel ending.
The “official” (Tour de France) climb ends at 1,840 metres.
It lacks the attraction of the classic route, but it offers a splendid view on (part of) that, once you have passed Villard-Reculas, as seen in the picture of Bend 7 above.
The start of this climb is in Rochetaillée, more commonly known as starting point for the climb up the Croix de Fer/Glandon.
Shortly after traversing the river La Romanche, you turn right (D44) and follow the direction ‘Villard-Reculas’.
From there, the climb is 20.5 kilometers long, with 1,130 altimeters (5.5%) but that’s a little ‘deceiving’.
You can see on the profile card that there’s a stretch traversing the valley between Villard-Reculas and Huez, which has no (net) altimeter gain.
Taking these 5 kilometers out of the equation, the average grade is around 7.8%, so do not underestimate this climb either.
Looking at the ‘raw’ numbers, it’s only 10% ‘easier’ than the classic route…
And yes, from Huez, you will join the remainder of the ‘classic route’, the final 5+ kilometers of it 🙂
Col de Sarenne
From the south, starting almost opposite of the climb to Les Deux Alpes, in Ferrand at the barrage du Chambon, you can get to Alpe d’Huez via the Col de Sarenne.
The official start is Le Clapier, where the Col du Lautaret also starts and it has the first 9 kilometers in common with that.
Starting there, it’s a 13 kilometer long climb, with an average of 7.5%, a very steep start and the final 4 kilometers averaging 9.5%.
After a 200 meter descend in the first 4 kilometers from the summit, there are some 5 kilometers of ‘rolling terrain’ left before you enter Alpe d’Huez.
