I know skiing is in kilometers but my Garmin is setup in miles.. so I skied 4.1 miles or 3 loops of the 2k course of man made snow at Wirth. It was fast snow at 6:30am.
I was surprised at the number of people out at that time. The trail is lit. A couple of the downhills were steep with turns in them. I fell 4 or 5 times and one of them was pretty hard and my hip hurts and had a small cut on it.
