Out of the 3 distances at Swiss Alps 100, this is the shortest and easiest. Runners will still cover a respectable amount of total elevation gain of 2'600 meter (8,550') but have a generous total cutoff time of 12 hours. The most difficult part by far is the 2 KM downhill after climbing to the highest point of the course at Tristul (2'575 m.ü.M.) at mile 17.6 (28.3 KM). If you are looking in moving from a marathon to a 50KM this could be your next race.
Starting in Münster at 1'327 m.ü.M. (4,353 feet) the course begins with a gradual downhill on farm/fire-roads and single trails with some occassional slight uphills. At 9 KM (5.5 miles) runners get the opportunity to cross over the 280 meter (918 feet) suspension bridge Mühlebach - Fürgangen. Soon after that they'll arrive at the Mühlebach aid station where the 50KM runners part with from the 100KM and 160KM field and start their 7.4KM - 1'040 meter (4.6 miles - 3,400') climb to the Schäre aid station.
Once you leave the Schäre aid station you have another 5.6 KM - 400 meter (3.5 miles - 1,300') climb a long downhill awaits until the Reckingen aid station. From there it's a rolling course to the Ulrichen aid station and then a slight downhill last portion to the finish line.
With a total elevation gain of 2,600 meter (8'550'), 50km runners will have a very generous cutoff time of 12 hours.
