This is Megaloops. The idea is to ride the 21km (mega)loop twice and head for home. For fun, in the past, we would split the group in two at Arkell and send one squad off 30 seconds ahead of the other. One group tries to catch while the other attempts to stay away until the end. It encourages teamwork. You could think of it as a TTT pursuit. They’re doing it at le Tour this year so why not? A rotating paceline works best for this. Come to the front when you are able, if not rest up. If you do rest up don’t pull through like gangbusters and gap the man (or lady) on front. Doesn’t help the cause. Bring a road bike, of course. Be safe, don’t overlap wheels.
