London to Brighton Bike Ride Time: Pace, Elevation, and Cutoffs

The London to Brighton ride is a classic 54–55‑mile roll from Clapham Common to the seafront, with one big hill—Ditchling Beacon—near the end. Most recreational riders finish in 4–7 hours, and a moderately fit cyclist can expect about 6 hours on the road. Organized events typically give generous time allowances (commonly a 7 pm cutoff), so even steady charity-ride pacing can make it comfortably. This Hiking Manual guide turns that headline timing into practical pacing bands, elevation expectations, start‑wave planning, minimalist gear, and a simple training plan—so you can arrive in Brighton on time and upright, without decision fatigue.
