I think that ice won't be a problem.
There may be some, in shady lanes where the sun doesn't get to it. But the roads are reasonably dry at the moment. At worst, we can walk over that. I avoid ice, but I've decided to come along for the ride. I'll be riding overnight to the start. That's how confident I am about ice not being a problem. At night, you can't see the ice until you're right on top of it.
On my ride home from work today, the dew on the grass was still frozen from this morning. But not even the untreated roads were icy.
It will be jolly cold though. My scarf will be in service. Wool and thermals are my friends.
See you there, hopefully.
I laugh at fog... and cheat by using my GPS to find my way around.
Fog isn't a problem.
Unless, like wowbagger and NSTN, you need to wear glasses.
I heard somewhere that squirting washing up liquid onto your glasses, then cleaning it off with a cloth until they are dry will stop them getting fogged up. Maybe you could try that?
