Richmond Marathon

The Richmond Marathon is part of the Richmond RUN-FEST series and is organised by RUN-FEST. The race starts inside the Royal Botanic Gardens, Kew and follows a scenic route alongside the River Thames before finishing in Old Deer Park, Richmond. The finish area features a family-friendly music festival, creating a festival atmosphere for runners and spectators alike. The event page for the Richmond Marathon includes downloadable course files (GPX/KML) so runners can preview the 2026 route.

The course is described by the organiser as flat and fast and is well suited to both first-time marathon runners and those chasing a personal best. The course profile notes a total ascent of 160 metres and a total descent of 160 metres across the full 42.195 km distance. The event is presented as part of the wider RUN-FEST weekend in September 2026, which also includes shorter distances and children's events. Entrants and charity partners list inclusions such as a technical T-shirt, finisher medal and chip timing on their respective entry pages.
