Really looking forward to hearing how you get on Paul, it's a tough day out but well within you I reckon.
I'm actually more concerned about some of the descents on skinny tyres though.
I'm far from the bravest descender but coming off Honister was absolutely terrifying - road corrugated due to the previous snow and ice, surface greasy after a light shower, rear wheel skipping about, 25% gradient and winding. Oh, and some loose gravel.
Hardknott wasn't much better. I'll admit without shame that after seeing someone leave the road and end up on her head I walked down, cutting across the apex of the hairpins - the route instructions recommend hard on the brakes as soon as you go over the top and with good reason.
It was a proper 'big day out' though even if I'm glad that I had a compact chainset fitted. I nominally rode with a friend but the reality was that I was faster on the climbs and he was much faster going down so we simply met up at the food stops with no significant wait either way. And there are so many riders that you're never really alone, even if at times you perhaps wish that you were.
As for the Four Seasons, that might make a good group ride in summer? Could also split it into two days if we wanted to make a weekend of it.
