A bit of an obvious warning re UK cycleways; they're not gritted.
I was riding on the Dee cycleway near Chester on Sunday and came off on black ice. I landed on my head cutting myself just above my right eye. I got off lightly considering. It could've been much worse. My bike was unscathed and I was able to ride home.
Watch out all you guys who are regular users. It's probably best to use the main roads until conditions improve.
