It's no different to people going skating on it FFS!
I remember years ago in a similarly bad winter watching loads of people ice skating on the frozen canals and waterways of Lincolnshire (my Grandad lived there and he used to tell stories of doing the same thing in his youth).
I rode a short section of the frozen canal near Marple on the way home from work on Friday. Not to show off (there was no-one else around), just because I could. I could see footprints on the snow-covered ice so it was a calculated risk and I probably won't get the chance to do it for another 10 years!
