Temperature: 1 degree at the start , -2 at the finish; light to medium snow fall
Conditions: wet surface during the first half, then very icy and slippery, dangerous frozen snow and ice on the last 100m
I ran on my own, but there were quite a lot of runners and hikers on the trail. I had to slow down at the end because of the difficult conditions. I tried it only once, but will come back as I ran the trail frequently since many years.
