L'Aussonnaise is a mixed road and trail race held in Aussonne, Haute-Garonne, a short distance from Toulouse. Participants can choose from a 5 km race up to a 21 km course, with an 11 km option, walking formats, children's races, and a team format also available. The event takes place during the cross-country season, but the routes are not highly technical, making them suitable for road runners seeking some nature without the challenge of a rough trail race.
The course incorporates both roads and paths, winding around lakes and through small wooded areas. The longer routes feature moderate climbing, with approximately 80 to 160 meters of positive elevation gain depending on the distance. Hybrid shoes are advised because of the varied terrain. Physiothrust Sport presents the event, with one euro from each registration donated to the association Y arrivarem. The finish area will offer food trucks and entertainment.
