First loop: 1:22 h ; second loop: 1:28 h
Trail was well marked; no problems to find the way.
Perfekt weather conditions: dry, 11 degrees and cloudy sky.
I could have safed 2 or 3 minutes which I needed to take photos and because of a dog attack.
Strava (back-up recording) shows only 23k as this was recorded with the mobile and the mobile GPS is not perfect.
