Well I'm at home now having packed the More Passes Than Mastermind about an hour and a half after the départ. I had cycled from Edinburgh early in the morning to Symington (about 53k) as the first leg of an ECE perm, but could not complete the 200k event.
Several factors decided it for me: I've had a cold all week, and though I was dosed up on max strength flu powders my energy levels were fading after about 70k (from Edinburgh); This meant I struggled to catch the rest of the group after starting a couple of minutes late. I could have carried on, and maybe caught up at Sanquhar but about 20k into the calendar ride my saddle started to twist loose. I spent quite a while trying to tighten the seatpost bolt but after another 5k it was loose again: maybe has a partly stripped thread. The prospect of trying to ride the event with that potentially happening frequently, or getting worse, did not appeal. So Iturned and headed for home.
Managed to ride back to Edinburgh but had to keep retightening the darn thing!
Anyway a pity as I was hoping to complete this event. Maybe next year!
