The 2026 Westonbirt Arboretum races turn the National Arboretum into a late-summer running festival on 6 September 2026. Runners can choose from four distances — a half marathon, 10km, 5km and a 1-mile fun run — all starting and finishing within the arboretum grounds. The routes follow solid stone forest tracks that feel almost like road underfoot but wind through varied woodland, rare tree collections and long, leafy avenues, giving all the visual richness of a trail race without technical terrain. With courses that are largely flat and well-marshalled, the event suits everyone from first-time 5k runners to half-marathoners chasing a time. Families and supporters can spend the rest of the day exploring Westonbirt’s grounds, making it as much a day out in nature as it is a race.
Races
The Westonbirt Arboretum 5km on 6 September 2026 gives runners and walkers a shorter, friendly distance on the same picturesque stone paths at Westonbirt, again hosted by Relish Running Races. This beginner-friendly loop captures all the magic of running through world-class tree collections in a compact, accessible package.
Also on Sunday, 6 September 2026, the Westonbirt Arboretum 10km offers a single-lap route on firm, mostly flat forest tracks starting and finishing within the arboretum, under the organisation of Relish Running Races. With its mix of shade, smooth footing and carefully marshalled paths, it’s a perfect late-summer 10K for both PB hunters and runners who want to linger in the scenery.
On 6 September 2026, the Westonbirt Arboretum Half Marathon sends runners on a two-lap 21.1 km tour of the National Arboretum’s stone forest paths, organised by Relish Running Races from the grounds at Westonbirt, near Tetbury. Largely flat with only gentle rises, this half showcases avenues of rare trees and sweeping woodland vistas in one of the UK’s most beautiful running settings.
