Trail running routes in Chilterns
Beech hangers, chalk and a surprising amount of climbing for somewhere an hour out of London. The Chilterns run north-east from the Thames at Goring to Hitchin, and the running is field edge and woodland rather than open hill — steep in short bursts, sheltered, and good underfoot for most of the year.
