Stage 17: Saint-Paul-Trois-Châteaux - Superdévoluy, 177.8k
At last, the race re-enters the Alps with a slightly disappointing stage. There’s nothing wrong with the Noyer-Superdévoluy combo, but to put as little as possible before it in a race with only five other mountain stages is… not the decision I would have made.The route
Today’s stage start, Saint-Paul-Trois-Châteaux, wins the misleading name award: it actually doesn’t have three castles, instead it was settled prior to the Roman invasion by the Tricastini and somehow that name evolved into Trois-Châteaux over time. It has been a town since that era, and was the seat of a bishopric until the French Revolution. Today, it’s essentially your average southern French town. This will be its fifth appearance, all stage starts in the past 14 years.

There’s some ground to cover between the start and the edge of the Alps, which is reached in Nyons. Here, the riders enter the Baronnies, the least developed and (highest massifs aside) most sparsely populated area in the French Alps. There’s some decent terrain to be found here, but you wouldn’t know it from the route, which sticks to the valleys as much as possible. Of course, the riders do need to climb a pass of sorts to get from the Rhône to the Durance basin… the Col de la Saulce, the long drag out of Verclause on the stage profile.

In Serres, the route leaves the Baronnies, and the landscape becomes less depopulated. The intermediate sprint is in Veynes, the first place that can be described as a town since Nyons, over eighty kilometres back.

After a short, easy descent down Col de la Freissinouse into Gap, the actually-hard part of the stage starts. Col Bayard is the highest point of the Route Napoléon, the route through the Alps taken by the former emperor after escaping from his exile on Elba that led to his brief return to power known as the Hundred Days. It is the same climb as the more commonly-used Col de Manse until the junction to Orcières on the profile below.

There isn’t much of a descent, rather a rolling section until the bottom of the main course of the day, Col du Noyer.

After a short descent, the riders take on the HTF to Superdévoluy. As you can see, it is not hard in the slightest.


A classic budget destination, Superdévoluy is a strong contender for ugliest French ski station. As anyone who’s been to the French Alps will be able to tell you, that’s quite an achievement. It has not hosted the Tour before, but we’ve seen finishes here coming from Noyer in the 2013 and 2016 Dauphiné.

What to expect?
Huge opportunity for any climbers that manage to make the breakaway on the flat. Col du Noyer is definitely hard enough for GC action, but it wouldn’t be a shock to see the big guns keep their powder dry for the final three days.
