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 6'250 meters 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 prudal 3.2 miles and 3697 feet uphill after the Binn aid station going on top of the Breithorn.
Finisher will receive a beautiful 3.5 inches medal. We also give out female/male age group awards (18-29, 30-39, 40-49, 50-59, 60-69, 70+). See the race weekend schedule page for the check-in and race starting times. The overall cutoff-time is 27 hours and there are 10 fully stocked aid stations. Finishers earned a Western States 100 qualifier if finished in 22 hour or less.
