Trail du Grand Ballon

The Trail du Grand Ballon is a 75-kilometer ultra trail race with 3,200 meters of elevation gain starting from Guebwiller, in Haut-Rhin. This major event in the Vosges calendar takes runners to the summit of the Grand Ballon, the highest point in the Vosges Mountains at 1,424 meters altitude, on a course that traverses all the characteristic landscapes of the Alsatian mountains.

Guebwiller, a small wine-producing town nestled at the foot of the Grand Ballon, is the ideal starting point for this adventure. The town, whose Romanesque and Gothic churches bear witness to a rich medieval past, is surrounded by grand cru vineyards. Runners depart from the historic center and quickly reach the forest trails that climb toward the summits.

The Trail du Grand Ballon course is a true summary of the Vosges. Runners successively cross the foothill vineyards, the beech and fir forests covering the slopes, the high-altitude chaumes where Vosges cattle graze, and the panoramic ridges from which the view extends over the Alsatian plain, the Black Forest, and, in clear weather, the Swiss Alps. The ascent of the Grand Ballon, the course's high point, is the race's defining moment, rewarded with a 360-degree panorama of striking beauty.

The 3,200 meters of elevation gain make this race a substantial challenge. The climbs are long and sustained, with sections of 600 to 800 meters of elevation gain in a single stretch. The descents, often technical on rocky mountain trails or through root-filled undergrowth, test quadriceps and concentration. The terrain alternates between exposed ridge trails, needle-carpeted forest paths, peatland passages, and chaumes crossings.

The Trail du Grand Ballon demands serious preparation and mountain experience. Weather conditions can be severe at altitude, with significant temperature variations between valleys and ridges. Fog, frequent on Vosges summits, can complicate navigation despite careful course marking.

The course crosses remarkable natural sites: the Markstein, a ski resort and starting point for many hikes, the Lac du Ballon, the oldest glacial lake in the Vosges, and the cirques of Seebach and Murbach. The fermes-auberges, mountain refuges where marcaires serve traditional meals, are emblematic waypoints where runners can refuel and regain strength.

Aid stations honor Alsatian gastronomy: Munster cheese, kougelhopf, tarte flambee, and Alsatian wines. The atmosphere is that of a major mountain race, with a spirit of solidarity and mutual aid that unites runners in effort. The Trail du Grand Ballon is a benchmark of Vosges trail running, a complete event that combines distance, elevation, and landscape beauty in a massif that fully deserves its reputation as a mountain for living.

Trail du Grand Ballon is a 75 km trail race with 3,200 m of elevation gain, located in Guebwiller, Haut-Rhin. The next edition is scheduled for 7 June 2026.
