I´m skiing on a weekly basis now in the winter here in Oslo, making up for last year when I had a bad achilles. This Sunday Julia and I went to Sognsvann just 5 km from my front door. This is a lake and wooded area leading to Nordmarka, a large natural National Park just outside the city limits. The route was 10.6 km and was actually mainly up hill and was quite icy on the steep sections as it has not snowed for a few days. This was quite annoying and the downhill section was not lit and was icy in the dark. Anyway we had a good 90 min workout at least. Next week we will be going to Nordmarka from Tryvann as the runs are nicer with more fun corners.
