What you’re in for
Farnham to Ashford on the North Downs Way, leaving the trail only twice in a hundred and three miles. Puttenham, Guildford, Ranmore Common, Box Hill, Reigate Hill, Merstham, Oxted, Knockholt Pound at halfway, then Wrotham, Holly Hill, over the Medway, Detling, Hollingbourne, Harrietsham and Charing. Acorn posts plus reflective tape and Centurion arrows. At least twelve aid stations with hot food at Knockholt and Detling. Thirty hours. The steep descents and the steps get slippery, so trail shoes.
