Up to Sognsvann with the T-bane then skied home, via Tryvann, Skjennungen, Ullevålseter, Hammeren, Grinda.
Bit of a steep climb to start with which combined with a lack of skiing over the last month made it a bit hard work.
I think there is probably close to 2 metres of snow in the forest, so even if it is showing signs of melting it might take a while
