Distance and timing basis
Ordered leg totals agree within rounding. Stop distances are approximate sums of rounded legs. Stops, delays, approach and any separate return travel add time. Basis: producer-declared routed record.
Reading history stays on this device. My road watch requires a separate selection; opening it does not subscribe this ride.
Distance and riding time are measured on the routed road. Check local closures and conditions before you ride.
A one-way ride of 181 km, Beaufort to Valloire - roughly 3 h 22 in the saddle. The highest point is 2,764 m. Cormet de Roselend and Col du Galibier are subject to seasonal closure - check it is open before you set off. A steady touring day rather than a sprint.
Scenic road chapters
Col du Cormet de Roselend → Col de l Iseran
The ground tilts up and stays tilted for 92 km. 797 m of it, taken steadily rather than in one wall — a steady rhythm suits this better than bursts. The height arrives whether you hurry or not.

Waypoint introductions and full write-ups
1. Col du Cormet de Roselend
The Cormet de Roselend is the pass of cheese and water. It lies in the Beaufortain massif, between the town of Beaufort and the valley of the Isère, and for much of the climb you are riding through the pastures where the cows that make Beaufort cheese spend their summers, wearing bells and grazing on alpine flowers. The cheese, which is aged in the valley, is one of the most prized in France, and it is the reason this valley is prosperous and well kept. A wheel, with its distinctive concave edge, is sold in nearly every village.
May refer to an earlier itinerary; verify against your selected route before riding.
Planning note
Col du Cormet de Roselend is where the day begins. Next is Col de l Iseran, climbing 797 m.
2. Col de l Iseran
The Iseran is the roof of the Alps, as far as paved passes go. At 2,764 metres, it is the highest of the great Alpine passes, a shade above the Stelvio, and the road over it was opened in 1937 to link the Tarentaise valley with the Maurienne, a feat of engineering that took years of work in short summers. It goes through the heart of the Vanoise National Park, France's first, created in 1963 to protect the ibex, which had been almost wiped out by hunters, and the park's work has been a success, as there are thousands now.

Planning note
Col de l Iseran comes up about 72 km into the recorded legs. The road climbs 797 m on the way up to it, steadily. Reckon on about 5 °C colder than the valley, and more in the wind. Nothing on this route is higher. Next is Col du Galibier.
3. Col du Galibier
The Galibier is the big one, and it knows it. At 2,642 metres this is one of the high gates of the French Alps, the saddle where the Maurienne valley to the north hands you over to the Guisane and the Briançonnais to the south, and the road crosses it by way of a short tunnel under the actual crest, or, for those who want the proper view, by the final few hundred metres of open hairpin that go over the top. The summit marker stands on the old crest, with a monument to Henri Desgrange, the founder of the Tour de France, who first sent the race over this pass in 1911. Cyclists still turn up in swarms to touch the sign, so expect lycra and an unhurried pace.

Planning note
The route ends here after 181 km. Reckon on about 4 °C colder than the valley, and more in the wind.
