London’s “Triple Loops” route is a large loop containing three more loops. First you hit the Greater London loop, then the Classique, then ride over Leith Hill to a loop which includes Box Hill. Descend Fox Hill, ride up through the Underground, then it’s a drag race to the finish.
The route is essentially flat for the first half, then very hilly for the back half. A bit like Zwift’s Richmond UCI course in that respect, except much longer.
