The 160KM distance will start in Gluringen at 1316 meters above sea level (4318 feet). The course begins with a gradual downhill on farm/fire-roads and single trails. After the first aid station Niederwald the 160K runner will make their way up to Bellwald and the their first amazing challenge crossing the Aspi-Titter suspension bridge . This bridge is 160 meter long, has 1'894 steps, and the valley below is 120 m deep. Have fun!

Once runners cross that bridge it's 4.8km and 760 meter elevation gain (3 miles - 2,500') to the Gletscherstube aid station. We are not kidding! The next few miles along the Aletsch glacier will make runner's eyes smile!

With the glacier behind runners will arrive at the Riederfurka aid station. If they have drop bags they'll find it there. After this aid station they'll enjoy a downhill to their second challenge crossing the Belalp-Riederalp suspension bridge . This one is 124 meter long and looking down they'll see the valley 80 meter below them. Piece of cake!

Being now used to suspension bridges all 160KM runners make their way up to the Belalp aid station. This is a very interesting aid station because from here they'll will have to make their way up towards Hohbiel and run around the Speichersee counterclockwise at 2780m (9120'), which is also the highest point on this course, and the back down to the Belalp aid station.

From there the runners are heading towards the Gebidem dam. They'll cross that dam, which is quite an amazing sight, and move towards the Riederfurka aid station again. From there it's a rolling course of 8.7km (5.4 miles) to the Kühboden aid station. From that aid station there's a long downhill into the lowest part of this course in Fieschertal at 1091 meter (3579').

Once passing through Fieschertal the runners cross yet another suspension bridge the 280 meter (918 feet) suspension bridge Mühlebach-Fürgangen . Soon after that they'll arrive at the Mühlebach aid station where they can find their drop bag if they have one.

From Mühlebach they run to Grengiols. Next up is "The Beast" a 1300 meter (4260ft) climb in only 10.3km (6.4 miles) with 14 switchbacks. Soon runners find the Breithorn aid station. 160KM runners will then run over the Saflischpass to the Rosswald aid station. After the Rosswald aid station climbing up to the Fülhorn presents another technical sections of the course where runners have to watch their steps for a few meters. After coming by the Breithorn aid station one more time they're down to the Binn aid station where runners can get their drop bag if they have one. The next 13.5km (8.3 miles) it's a long uphill, followed by a short downhill and a short uphill again to the Chäserstatt aid station.

Once they leave the Chäserstatt aid station they'll run over to the Blinnental aid station. This part of the course runners need to be particular attentive to the course because it can be confusing at times not following a trail for about 2KM. After Blinnental runners reach the Münster aid station where they can see their crew for a last time. From there it's 7.7km (4.7 miles) to the finish line.

With a total elevation gain of 10440 meter (34250'), 160KM runners will have a cutoff time of 48 hours.
