Originally I planned to do the run as an unsupported partner fkt, but finally it turned out as supported. I was accompanied by two buddys who dropped out (one until km 17, and one until km 36). Also I ran out of water on the second half, and thus got some water from a tab at a private house (two sources that I planned with were dry).
All in all a nice course. Especially in the first part some very nice trails and amazing views of the lake and the Alps. The second half was more on forest roads. Weather was nice, ~20 degrees, perfect in the forest, quite warm in the sun. I carried all my food with me, and filled up water three times. In the first half there are enough publicly available possibilities for water. We aimed first for a pace of 5:15 but then got slower in the second half.
