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. Then you’re back through the start/finish banner to do it all again!

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.

Distance: 40.8km (25.4 miles)
