Yes, I found out how bad it was Wednesday evening! Luckily, it had started to frost up so some bits I managed to 'glide' over, but other bits I sunk into up to my ankles. New route is about 8 mins longer (running quite slowly), went down to canal near paper mill, cut through woods and down to Chadkirk, over new bridge, through the bog, and up towards Rose Hill. Not too bad, but will be glad when the canal re-opens!
