About This Race

The 35K distance offers runners a substantial alpine challenge that bridges the gap between the shorter scenic routes and the ultra distances, requiring sustained effort over technical terrain without the multi-day preparation demands of longer formats. This distance typically attracts experienced trail runners seeking to test their mountain legs on classic Swiss terrain while maintaining manageable time commitments. Runners can expect several hours of varied alpine conditions, making it an ideal stepping stone for those building toward longer UTMB World Series events or seasoned runners wanting a focused day in the mountains.
