Trai'elle is a women-only trail race in Kaysersberg, beginning at Salle Theo Faller. It features a 21 km course with 820 m of elevation gain. The event is conducted in French, and spectators are encouraged to gather in Kaysersberg to support the participants. The 21 km race costs 30 euros to enter, with registration managed via Sporkrono.
The event provides three trail running distances: 8 km with 260 m of elevation gain, 14 km with 550 m, and the 21 km course with 820 m. A Nordic walking option follows the 8 km discovery trail route; walkers begin separately, are not timed, and can proceed at their own pace. Nordic walking is open to all, while the running races are designated as a 100% female solidarity event. Two euros from each runner's entry fee is donated to the League Against Cancer, and food services are available at the venue.
