I took my rucksack and some extra clothing. This turned out to be a smart move. It was quite breezy and with the wind chill factor taken into account it was almost freezing, and especially more so by the time the sun was setting. You can see traces of an earlier frost, left over from the foggy days, on the forest path in the second photo down.
The first photo shows where I left the road. I took the path to the left. The second photo is the trail leading to the radio mast (see third photo). That was the highest point of the run. From there it was downhill to the village of Kahlenbergdorf and the pub (fourth and fifth photos). At the pub I had a bowl of soup.
I then jogged to the village of Grinzing using a trail through the local vineyards. I reached the s-Bahn train station just before twilight. Forty minutes later I was back home.
