The Trail du Xarnegu begins and ends in Bergouey-Viellenave, a village in the Pyrenees-Atlantiques of southwest France. This event offers two trail-running distances: 15.5 km and 8.5 km. Additionally, there is an 8.5 km sports walk for those seeking a similar outdoor activity without the competitive aspect.
The 15.5 km race involves a 411-meter climb, making it the more challenging option. The 8.5 km route has 166 meters of elevation gain. The walking course follows roads and paths. The schedule has walkers starting first, followed by the 15.5 km runners, and then the 8.5 km runners. The short race is open to participants from the cadet category (ages 16 and up), while the longer race is for juniors and older (ages 18 and up).
