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.

Waypoint introductions and full write-ups
1. Chamonix
Mont Blanc does not so much loom over Chamonix as lean on it. The valley is a deep, narrow trench of the Arve river with the highest peak in the Alps, just under 4,810 metres, standing right at the top of it, and the glaciers come down so close that you can see the cracks in the ice from the main street. Modern mountaineering has a birthday here. In 1786 two local men, Jacques Balmat and Michel Paccard, reached the summit for the first time, and the town has been selling the idea of going up high ever since. In 1924 it also hosted the first Winter Olympics.

Planning note
Chamonix is where the day begins. Next is Les Marais de Saint-Jorioz.
2. Les Marais de Saint-Jorioz
Lake Annecy is often called the cleanest lake in Europe, and on a summer day its water is such a startling shade of turquoise that it looks retouched. The lake fills a long valley among the limestone mountains of Haute-Savoie, with the town of Annecy at its northern end, and its western shore, around Saint-Jorioz, is a flat area of reeds and meadows, the Marais de Saint-Jorioz, where prehistoric people built villages on piles. The remains are part of the Prehistoric Pile Dwellings around the Alps, listed by UNESCO in 2011, and lie hidden under the water and the marshes.

Planning note
Les Marais de Saint-Jorioz comes up about 115 km into the recorded legs. Next is Le Crêt de Chatillon.
3. Le Crêt de Chatillon
The Crêt de Châtillon is the summit of the Semnoz, the long wooded mountain that rises above the western shore of Lake Annecy, and from the top, at around 1,700 metres, the view on a clear day is one of the finest in the French Alps: the whole lake below, the Bauges and the Aravis around, and, to the east, Mont Blanc in all its glory. Sites with names like Châtillon and Les Mongets along this shore preserve the remains of villages built on the edge of the lake thousands of years ago.
May refer to an earlier itinerary; verify against your selected route before riding.
Planning note
At least about 121 km into the recorded legs you reach Le Crêt de Chatillon. Next is Secteur des Mongets.
4. Secteur des Mongets
Sevrier, on the western shore of Lake Annecy, is home to an unusual industry: bells. The Paccard foundry, which has been casting bells since the late eighteenth century and moved to Sevrier in the 1980s, has made bells for churches and carillons all over the world, and its museum explains how they are designed, cast and tuned. It is a curious contrast to the quiet lakeshore just below the village, where the Secteur des Mongets marks the remains of a prehistoric village built on the edge of the lake, now under water. It is one of the sites included in the World Heritage listing of the Prehistoric Pile Dwellings around the Alps, and divers have found wooden piles, pottery and tools in the lake bed.

Chamonix closes the day.
