We ran Etappe 3 and 4.
Etappe 4 was 2:51:58; incl. short break (1-2 min) between Etappe 3 and 4 and a "failed attempt" to find shelter from the heavy rain (app. 10min).
Conditions were good at the beginning, dry and not too warm on Etappe 4. For the last 8k we had very heavy rain with partly flooding of the single trails.
The trail is well marked.
There are a lot of beautiful single trail sections and some stunning views.
