i started this course yesterday morning (28. August) at 08:15 a.m.
Unfortunally my Garmin Fenix 5x seemed to struggle a little bit by finding the GPS on the first kilometer, thats why the track is "dodging" there a little bit and starts a little too late. I started my run exactly at the courses starting point right at the northernmost corner of Neheims "St. Johannes Baptist" cathedral, as you can see in the first pictures i uploaded.
I did the run alone, brought 2 liters of water with me in my backpack and bought additional water and softdrinks along the course. In Büren (from Km 62 to 63,7) i had to add some extra meters to reach a filling station for buying water. I went there and back and continued the course on the same point where i left it before. My fenix was recording the whole course from start to finish continously without being stopped in between.
