This year the 10K and the Half Marathon road races will both take place on Sunday 19th September 2021 under the umbrella of the Great Bristol Run. This will again involve road closures close to Merchants Landing. Full details are available in this leaflet (PDF).
The organizers have assured us that they will again be operating a carefully controlled access lane along Wapping Road to exit via the roundabout by The Louisiana. Obviously there will only be a left-turn at the Louisiana roundabout, at least until 13:30 when Cumberland Road will be re-opened.
