Le Trail des Mousquetaires 2026

Le Trail des Mousquetaires is a mid-October trail running event in the Gers department of Occitanie, in southwest France, with race listings placing it around Auch and Montegut. The program features short and middle-distance off-road courses, with options such as 8.5 km, 13 km, and 25 km on one listing, and 11 km, 16 km, and nearly 28 km on another. It is not just for runners: the event also includes walking routes, and some formats can be done solo or as a relay. The courses use forest and natural terrain in Gascony, with enough climbing to make the longer races feel like real trail efforts: the 25 km route lists 850 m of ascent, while the Montegut long course is just under 28 km with 606 m of ascent. The race leans into its Musketeers theme, with names like Les Foulées d'Athos, L'Escapade d'Aramis, and La Balade de Portos, plus the slogan "Un pour tous, tous pour un !" The 13 km option is the most popular in the source material and can also be entered as a corporate team event, so the field is likely a mix of local trail runners, walkers, relay teams, and workplace groups.
