The last ten days have been unusually cold. Sheffield used to get deep snow that lasted for days in the 1980s but that's been uncommon since I moved here in the early 1990s. At first the snow was pretty and it was a pleasure to be in the woods, even if the extra effort reduced how far I'd run. But, over the last few days almost all paths have become slippery with ice due to pressure from footfall and repeated thaw-freeze cycles. Twice I've been out and cut short my run due to fear of falling.
Paths on less popular routes are barely trodden but reaching them has become increasingly difficult.
