I ran the SeeGang hiking trail from Überlingen to Konstanz on saturday (13.06.2020) in 05:04:49. Overall it went very well, except that I got confused about which way to go at about 9km in and lost a few minutes there. I carried all my food from the start and refilled my water twice at drinking fountains in the forest. I was alone for the entirety of the route.
