Devils Dyke is a dramatic 100‑metre, V‑shaped valley on the South Downs that serves as the spine of a three‑hour, guided cycling loop; the ride mixes steep descents and climbs, high ridge riding with sea views, stops in historic villages and a pub break, and is paced to your ability.

What the day feels like

What the three hours feel like

After a brief test ride to confirm comfort on the bike, the group transfers (or rides, depending on numbers) to Devils Dyke, drops into the 100‑m deep valley and follows lanes and ridge paths through Poynings, Fulking and along the South Downs Way; there are purposeful stops — a pub break at the Royal Oak, a spring in Fulking, an ancient flint oven, and the remains of an isolation hospital — before returning to the Devils Dyke car park for a finishing photo. The route covers roughly 20–25 km and the on‑bike time is about 2–2.5 hours within the three‑hour window, with the guide accommodating pace and route to the group's ability.
