The Heathrow Airport Loop is the perfect setting for a high-tempo time trial with a relatively unimpeded flat loop around the airport.
This relatively short cycling route is an introduction to the Surrey Hills and Box Hill in particular. The route climbs up to Ranmore Common, down the other side before the zig zag climb up to Box Hill. The route returns back to the start via Epsom.
The London to Rye one-way cycling route heads out over Crystal Palace and Biggin Hill, into the Kent Hills and beyond, taking a very picturesque route to the coast.
The Frensham Pond cycling route in the Surrey Hills heads out to the heathland and ponds beyond Guildford. After one large climb up Staple Lane to the Shere Woodlands the route turns away from the hills and begins a rolling route. Looping wide of Guildford, it heads through heathland to the area south of Godalming. From there it takes a loop around the ponds at Frensham.
Following the same alternative route out of London as the Bayley Hill Loop but this time going on to Shoreham for a wider circuit back to London.
