Mountain stages of the 2023 Tour de France

Post last updated:

This page showcases all the mountains and climbs for the 2023 Tour de France. The route was announced on 27 October 2022 and promises plenty of action in the mountains once again. This page reflects the information currently available and will be updated periodically as more information is released about the race.

I have been lucky to experience the thrill of watching the Tour de France on multiple mountain stages and am looking forward to 2023. My toughest descision will be which mountain to choose to spectate. In the Pyrenees the 2023 race returns to the slopes of the iconic Col du Tourmalet, while the race returns to the slopes of Le Puy de Dôme for the first time since 1988.

In 2023 the riders will be faced with the mountains in the first week when the hit the Pyrenees. It will be interesting to see how this shapes the race given there will still be a long way to the finish line. This year also sees a mountain stage on the day before the finish which will test the strength and resolve of all the riders before the final stage in Paris the following day. It will be interesting to see it all play out and I can’t wait until July.

A brief history of the mountains in the Tour de France

In most editions of the Tour de France, the mountain stages are where the race is won or lost. A single bad day for a rider in the mountains can see them lose minutes to rivals and an end to their title bid. On long mountain climbs, there is nowhere to hide and any little chinks in a rider’s armor are usually found. Over the years climbs such as Alpe d’Huez, Col du Galibier, Mont Ventoux, Col du Tourmalet, and Col d’Aubisque have become synonymous with the race.

The mountain stages are some of the most popular for people to watch the race and there are many iconic images of riders navigating a sea of spectators. It is estimated that many hundreds of thousands of fans line the mountain roads as they twist and turn their way to the summit. On rare occasions, fans get a little too close and bring a rider down.

First mountain stage in the Pyrenees

The mountains first entered the Tour de France in the 8th edition in 1910. In that year stage 10 started in the Pyrenean town of Bagneres de Luchon and climbed Col du Peyresourde, Col d’Aspin, Col du Tourmalet, and Col d’Aubisque before finishing 326km later in Bayon. Octave Lapize finished the stage first in a time of 14hrs 10mins. No mean feat given that all the mountain passes were dirt roads back in those days and the bikes had nowhere near the range of gears modern bikes now have.

Inclusion of the French Alps

While the organizers deemed the addition of the mountains to be successful the riders were less impressed and there were protests in 1910 about the stage. Nevertheless, in 1911 the French Alps were added to the race with the inclusion of Col du Galibier, Col de Castillion, and Col de Braus. This was in addition to the stage in the Pyrenees.

Since those early days, both the Pyrenees and French Alps have featured in the race annually. In later years climbs in other regions such as the Jura, the Vosges, and the Massif Central have been added to the race. The Pyrenees and French Alps have generally taken turns in being featured in the all-important last week of the race.

Famous climbs and the 2023 Tour de France

There are a number of iconic climbs from the Tour de France that everyone loves seeing in the race. Unfortunately they don’t all make it in every year but we thought I would go through and let you know which ones made the 2023 race and which did not.

Climbs in the French Alps

Alpe d’Huez will not feature in the 2023 Tour de France and was last included in 2022.

Col du Galibier, like Alpe d’Huez featured in the 2022 Tour de France and will not be back in 2023.

Col d’Izoard has not been included in the Tour de France since 2019 and again misses out in the 2023 Tour de France.

Mont Ventoux was climbed twice in the 2021 Tour de France and is not included in the 2023 race.

Climbs in the Pyrenees

Col du Tourmalet, the most climbed mountain in Tour de France history, will once again feature in the 2023 Tour de France. It’s going to be a busy year for the mountains with 3 grand tours, Tour de France, Tour de France Femmes and Vuelta a Espana, all using the mountain for stages.

The Col d’Aspin is also back for the 2023 Tour de France and will be the warm up act before the riders head up the Col du Tourmalet. It was also used in the 2022 Tour de France.

The Col d’Aubisqe last appeared in the 2022 Tour de France and is not included in the 2023 race.

Categorization of Tour de France climbs

Each of the climbs is given a categorization which is an indication of the difficulty of the climb. Hors category (HC) are the toughest climbs followed by category 1, category 2, category 3, and category 4. A category 1 climb will be harder than a category 3 climb so the lower the number the harder the climb. A climb can change categorization based on how far into a stage it might be. For example, a climb could be considered a category 2 climb if it comes early on in the stage when riders have fresh legs, or a category 1 climb if it comes towards the end.

The climb categorization also comes into play when awarding points in the Polka Dot jersey competition. For example on an HC climb the first rider over the top will be awarded 20 points while on a category 4 climb the first rider will be awarded 1 point. On an HC climb points are awarded for the first 8 riders while on a category 4 climb only the top rider receives any points. There is a sliding scale of points and positions between HC and category 4.
