Ultra Trail Grand Colombier is a mountaineering competition that connects ridges, forests, and valleys in the Buget region of France.
The long street course passes through several villages and rises to the ridge of Grand Colombier.
A narrow path in the forest, a path around farmland, and a terrain with lakes and waterfalls connect the boundaries between mountains and villages.
The representative event, 120km course, has a cumulative altitude gain of 5,000m.
Starting from the old streets of Belley, we pass through Arbois-en-Busées and hilly villages with vineyards and forests.
Near Inimon, you can see a sloping mountain road and a view of Bujet, and on the Hauteville Plateau, meadows and forests spread out widely.
Finally, it leads to Quilos near the Rhone River.
The 30km trail takes a route up from Sessel towards Grand Colombier.
It is a sport that starts from a riverside village and moves to the mountains and forests, and Corbono,
a grape growing area, and Anglesfort at the foot of the mountain appear in the description of course.
The shorter gravel run runs along the Rhone River, while the 10km event is centered around Quilloz.
Depending on the sport, whether the weight is placed on the mountain ridge or the riverside varies.
In the long-distance category, there are not only individual races but also team relays.
Each runner completes the entire route as a team, covering parts of the mountainous terrain.
Rather than aiming only at the summit of one mountain,
this competition shows the long route that connects the highlands of Busee, rural areas, and the riverside.
