The mountain was really treacherous today. The snow and ice has been melting and re-freezing the last couple of days, and the path was like an ice rink. When I wasn't skating, I was plunging into slushy melted snow/ice (my socks are damp and brown!) or treading in horse muck - Lovely! But I did manage to run for a minute and walk for 4 up the hill as far as the bridge, then resumed my 4 minutes running followed by 1 minute walking back. Unless it snows again soon, or alternatively thaws completely, I don't think the Uetliberg route is very good. May need to find an alternative!
