The last weekend of September, Annecy will host one of the most iconic sporting events in Haute-Savoie. On September 26 and 27, 2026, the International Triathlon of the Lake Annecy will bring together several thousand participants, from the best amateur triathletes to families coming to cheer the competitors. Between the crystal-clear waters of the lake, the panoramic roads of the Bauges, and the lively quays of the old town, the event promises once again a magnificent spectacle.
An exceptional late September 2026 edition scheduled
Created in 1987, the International Triathlon of Lake Annecy is one of the most renowned competitions in France. Usually held at the beginning of summer, the event will exceptionally take place on Saturday, September 26 and Sunday, September 27, 2026, a calendar change linked to the G7 organization in Haute-Savoie a few months earlier.
Led by the Annecy-based club Les Hydros, this event attracts each year athletes from all over France but also many European countries, attracted by a course considered one of the most beautiful on the national circuit.
A unique setting between lake and mountains
Few events offer such a spectacular setting. The swimming part takes place in the particularly clear waters of Lake Annecy, often presented as one of the purest lakes in Europe. Competitors swim at the foot of the mountains before reaching the transition zone close to the Pâquier.
The cycling course then takes triathletes on the hilly roads overlooking the lake, with a demanding route that notably crosses the Bauges Regional Natural Park. The technical climbs and descents offer remarkable views of the lake and the surrounding peaks.
Finally, the running race runs along the lake’s shores and the famous gardens of the Impérial Palace before passing near the Pont des Amours, under the cheers of a constantly large crowd.
A program for all levels
The Annecy Triathlon is not only aimed at the most experienced athletes. The weekend is organized around several formats to allow as many people as possible to participate:
- Youth Triathlon on Saturday;
- introductory events;
- paratriathlon;
- Olympic distance Triathlon M individually;
- Triathlon M in relay, with male, female or mixed teams.
The flagship event, scheduled for Sunday morning, follows the Olympic format:
- 1.5 km swimming
- approximately 43 to 47 km cycling depending on the chosen route
- 10 km running
The cycling course includes nearly 770 meters of positive elevation gain, making it a particularly selective triathlon despite an accessible distance.
More than a competition, a true celebration of sport
Throughout the weekend, the atmosphere is particularly friendly on the quays of Annecy. Spectators can watch several starts, cheer competitors on the different parts of the course, or enjoy the many activities set up around the partner village.
Families especially appreciate the events reserved for the youngest, which allow discovering triathlon in a safe environment.
The organization also relies on the commitment of several hundred volunteers mobilized by the Hydros club, a factor that greatly contributes to the reputation for friendliness of this competition.
A significant tourist impact for Annecy
The International Triathlon is also a major event for the local economy. Each edition generates several thousand overnight stays in hotels, campsites, and holiday rentals in the Annecy urban area. Restaurants, shops, and tourist activities also benefit from the presence of athletes and their companions.
Organizing the race at the end of September also helps extend the tourist season after the summer holidays, while offering often ideal conditions for outdoor sports practice: milder temperatures, lighter tourist traffic, and autumn colors beginning to appear around the lake.
