Pace yourself. Do not sprint away from the start line like you’re being chased by a angry goose. You’ll regret it by mile 12.
Eat constantly. Bring flapjacks, bananas, and jelly babies. Your body is a furnace, and it needs fuel. A hungry cyclist is a grumpy cyclist.
Wear padded shorts. Your bum will thank you. In fact, your bum will sing a song of gratitude after the ride. Trust me on this.
