I've been known to spend a few weeks cycling John O'Groats to Lands End, with no training, on a £100 commuter bike. Did I enjoy all of it? No. Have I ridden a bike since? No. If you asked me the question though...I'd do it all again in a heartbeat.
One of the most satisfying things in my world is the content face of someone devouring something I've cooked for them. Be it a soul warming beef stew in the winter, or ferocious jerk chicken on the barbie in the summer (with added charcoaling, of course!)
