You're thinking 50KM is a bit too short and 160KM is a bit too long. So the 100KM will fit you nicely but don't underestimate the course. With a total elevation gain of 6'570m (21,550 feet) you will be tested along the course.

Along your journey you will be enjoy incredible views like running along the Aletsch Glacier, which is part of the UNESCO World Heritage, and traversing over the 160 meter (524 feet) Aspi-Titter suspension bridge and the 280 meter (918 feet) suspension bridge Mühlebach-Fürgangen .

The most challenging part is, perhaps, the distance between the Reckingen and the Chäserstatt aid station. With a distance of 16.8KM (10.4 miles) it's the longest distance between two aid stations but also has a 1320 meter (4330 feet) uphill and then a 832m (2729') downhill. And, of course, the prudal 5.3km (3.2 miles) and 1127 meter (3697 feet) uphill after the Binn aid station going on top of the Breithorn.

Finisher will receive a beautiful 9cm (3.5 inches) medal. We also give out female/male age group awards (18-29, 30-39, 40-49, 50-59, 60-69, 70+). And the DFL (very last finisher) will get a WhiteAlps Sport Rush-7 (black) hydration pack and a full-size version of a Hit!Balm product.

See the race weekend schedule page for the check-in and race starting times. The overall cutoff-time is 27 hours. Finishers are official UTMB 100K qualifier and if finished in 22 hour or less they earned a WS100 qualifier .
