The West Wycombe Loop cycling route heads up the Thames Valley towards Marlow where it then makes a beeline to the edge of the Chilterns for a bit of climbing before the long descent back to London via Henley.
This gravel route broadly mirrors the Frensham Pond Loop route in the Surrey Hills section but this time favours off-road tracks, exploring more of the heathland and Frensham Common itself in the south-western corner of Surrey.
Not content to go up Leith Hill once? Try going up and down it eight times from different angles. This is a gruelling ride with little recovery between climbs and nearly 2500m of elevation.
The Henley Loop cycling route is another longer but fast flowing variant that heads, south of Windsor Great Park to Wargrave and then rejoining the Thames at Henley.
This gravel route heads up past the lakes and marshes of the Lee Valley before looping back down through Epping Forest. The route up the valley passes the Walthamstow Wetlands, Waltham Abbey, Lee Valley Country Park and the River Lee Navigation canal. The return leg heads first out into open farmland before heading right through the heart of Epping Forest before back into London.
The Aldbury Loop cycling route heads north out of Regents Park and Hampstead and skirts south of Watford, out into the countryside and the eastern, Hertfordshire, end of the Chilterns with a loop around Aldbury Common back to London.
