10 km de la bastille - Grenoble 2026

The 10 Kms de la Bastille is a 10 km trail race held in Grenoble, France, typically in October. Participants can choose between a solo 10 km run or a two-person team event over the same distance. Both options feature approximately 500 meters of elevation gain. For those seeking shorter distances, the event includes a 600 m race suitable for children or beginners, a 1.5 km race for a brief challenge, and an 8 km walk for individuals who wish to enjoy the mountain scenery without competitive running. The race is named after the Bastille, Grenoble's historic hilltop fort overlooking the city at the edge of the Chartreuse massif. This fort, constructed in the early 19th century on the site of older fortifications, is surrounded by cliffs and steep terrain, making it an appropriate venue for a climbing trail race. Runners can anticipate forest trails and natural paths, distinct from a typical flat road 10K, though the event is also presented as an opportunity for conditioned runners to achieve fast times. The competition welcomes participants of all abilities, with the relay format allowing pairs to share the effort, and the shorter races encouraging younger participants to engage in the event.
