The Hatfield House Loop cycling route heads up through North London via the Swains Lane climb in Highgate, and then heads directly up through Potters Bar to the Hertfordshire countryside just south of Hertford and Welwyn Garden City. The route passes Hatfield House before the southerly leg heads back to Regents Park via Hampstead Heath.
The Fairoaks Airport Loop cycling route goes south of Chertsey out to the airfield at Fairoaks before looping back round for the same fast return route. There is an optional café stop for small groups at the Hangar Café at the airport.
Rolling hills without any steep climbs are the order of the day for this HITR route.
The Biggin Hill Loop cycling route is a relatively quick blast out of South London, around the top of the first ridge of the Downs by Biggin Hill.
