Yeah, you are correct. Back home now. Wheels fell off badly, not the PF, which actually felt improved after Honister, not the atrocious weather, they fell off during the little initial ascent onto the cliff top at ST. Bees. They felt unusually tired for the three days prior to starting but I couldn't figure out why and thought they would be ok once I got going. Not to be, by the time I stopped they had been so painful (Quads) for a long, long way that I knew I would do some serious damage of I carried on.
