I packed. My sincere apologies for lack of notice to organiser/helpers - I couldn't find a phone number on routesheet or brevet card, so texted Henry to pass on the message, and then I realised on waking this morning that I'd sent a text message to Henry's OLD number so it wasn't relayed that way either.
Started getting heart palpitations on the climb to Llanberis, scared the shit out of me, chest was hurting and I was getting short of breath. Upon stopping and phoning the wife, I kind of realised that I'd not really been at 100% all day and was fully anticipating grinding to a halt at some point through illness. so I set the GPS for Bangor and rode straight there, hopping the 8pm train for the motherland (Birmingham) where wifey came to rescue me and take me back to darkest zummerzet.
Feeling rather dejected/gutted right now.
