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 2km downhill after climbing to the highest point of the course at Tristul (2'650 m.ü.M.) at mile 17.6 (28.3km). 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 9km (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 and then make their way to the Chäserstatt aid station.
Once they leave the Chäserstatt aid station they'll have another 8.5km - 865 meter (5.2 miles - 2,838') climb and a 3.5km - 830 meter (2.1 miles - 2,720') downhill until the last aid station Blinnental. From there it's an almost mostly downhill run to the finish line.
Once you leave the Schäre aid station you have another 5.6km - 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 2,050 meter (6,720'), 50KM runners will have a very generous cutoff time of 12 hours.
