I started with two fellow runners (both female) in Meggen on Saturday, 11.07.2020 10:00. We ran together for the first 40km, after that I took off on my own. We were supported by a crew car and resupplied at km 28, 52, 75, 97, 114 and 134. Additionally there were some fountains along the route, but it is advised to bring enough water since there are long stretches (> 20km) without any water supply. Due to falling rocks some short sections of the original trail around Gersau were closed, but the alternative routes were clearly marked and followed the original route closely, adding a couple of meters of elevation gain. The part between Vitznau and Weggis was difficult to run due to the technical terrain and heavy rainfalls the week before, it's definitely advised to bring good trail shoes, even if > 80% of the trail are relatively smooth. I arrived back at the start in Meggen on Sunday 12.07.2020, 08:13.
