The race

The Churfirsten Trail Run starts in Unterwasser in the Toggenburg valley and offers four distances: a short 5.2 km Thur Trail, a 13.2 km Klang Trail, the 24.2 km Panorama Trail (1172 m gain), and the CT43 marathon at 43.3 km with 2910 m of climbing. Both the CT25 and CT43 sold out for the 2025 edition, so early registration is worth considering.
