The Aldbury Loop cycling route to the Chilterns 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.
It’s a generally rolling route with the occasional steeper climb.
Start point: Espresso Café, Regents Park
Suggested café stop: Church Farm Café (64km), just before Aldbury
