At the end of a day with a groggy head. This cold outing cleared my mind somewhat.
It’s certainly time to change to winter tyres. The mud is soft enough to make gravel tyres too slippery. I can still remember how much better the Schwalbe Rocket Rons are than the original set. They are notably slower on tarmac however.
