The Pyrénées Vallée des Gaves Trail is a trail running series in the Vallée des Gaves, French Pyrenees. Races are held near Lau-Balagnas in Hautes-Pyrénées, Occitanie, during early April. Participants can choose between a 10 km or a 20 km trail course.
The 20 km race attracts the most attention, serving as the primary option for runners seeking a longer distance. The 10 km offers a shorter participation in the same race weekend, having previously seen over 100 finishers.
