May 25, 2025,Trail (Treffendel)

Resuming the 2024 Serein Valley Trail in Treffendel.
Still as tough but a little faster than the first time. It's not easy to find the right trails when the signs are gone; I took the wrong path several times.
In any case, a great spot, magnificent landscapes and forests, top-notch climbs and descents.
23km, 525m+.
