I can but dream of 18mph average!!! Just returned after a lay off so only averaging about 14-15mph but never get better than about 16mph avg. Crap or what!!!
Anyway, got my first MTB ride out tonight since my 3 month lay off. Not confident that I'll keep up with the lads (so they may get a bit cheesed off with me lol) but it'll be a lovely night for it over the Yorkshire moors Looking forward to it in an insane sort of way!
