IMPORTANT COURSE CHANGE NOTICE: The small Hellerbrigga bridge between the Grengiols and Mühlebach aid stations is damaged and closed. For this reason, all runners in the 100 km and 160 km categories will have to take a short detour to bypass this bridge. This detour adds 1.7 km to the distance and 87 metres to the elevation gain. However, none of the aid station or finish line cut-off times will change. The downloadable GPX files below reflect this change.

The Swiss Alps 100 160KM is an ultra-trail masterpiece, pushing runners to their limits while rewarding them with some of the most breathtaking views on Earth. This relentless course takes you deep into the heart of the Swiss Alps, traversing rugged mountain passes, crossing three jaw-dropping suspension bridges—Belalp-Riederalp , Aspi-Titter , and Mühlebach-Fürgangen —and offering panoramic views of the UNESCO World Heritage Aletsch Glacier , the largest glacier in the Alps.

Runners will face a staggering 33,300 feet of elevation gain, mirroring the challenge of climbing Mount Everest from sea level! But for those who embrace the climb, the reward is pure magic—pristine alpine lakes, towering peaks, and trails that test both grit and spirit.
