Are you ready to take on one of the most spectacular 50KM ultra courses in the world? The Swiss Alps 100 – 50KM is an unforgettable journey through the stunning landscapes of the Oberwallis region, packed with 3'210 meters of elevation gain that will test your endurance and reward you with unparalleled beauty.

From the start, runners ascend into alpine wonderlands, weaving through rugged mountain trails and lush valleys. The course offers breathtaking views of the UNESCO World Heritage Aletsch Glacier , the largest glacier in the Alps, stretching over 23 kilometers (14 miles) of icy grandeur. As you traverse ridgelines and technical terrain, the sheer scale of this natural masterpiece will leave you in awe.

Adding to the thrill, the race crosses two exhilarating suspension bridges: the Aspi-Titter Bridge , a 160-meter-long (525-foot) passage that soars above the roaring Massa Gorge, and the Mühlebach-Fürgangen Bridge , offering panoramic views of Switzerland's oldest wooden village and the surrounding peaks.

With six fully stocked aid stations, you'll be fueled and ready to conquer every ascent and descent. The 15-hour cutoff allows ample time for both competitive runners and determined adventurers to complete the challenge.

Finishers will earn a beautifully crafted 7cm (2.7-inch) medal, a hard-earned token of their achievement. Plus, the top runners in each male and female age group (18-29, 30-39, 40-49, 50-59, 60-69, 70+) will take home special awards.

The Swiss Alps 100 – 50KM isn't just a race—it's an adventure through some of the most awe-inspiring landscapes on Earth. Are you up for the challenge?
