The Jubilee River July Run is a six hour timed trail event organised by PHOENIX Running and based at the Jubilee Riverside Centre in Slough. Runners complete as many or as few laps as they choose of a flat out and back course, making the event suitable for everyone from first time endurance runners to experienced ultra marathon competitors.
Each lap covers approximately 5.24 miles along the Jubilee River on wide crushed stone riverside paths. The route passes through open countryside towards Dorney Wetlands before returning to the start, offering uninterrupted riverside running with views towards Windsor Castle. The flat terrain and flexible format allow runners to tailor the challenge to their own goals, from a single lap to an Ultra Marathon distance within the six hour time limit.
All finishers receive a bespoke medal regardless of the distance completed. Combining a scenic riverside setting, a flat and accessible course and the flexibility of timed endurance racing, the Jubilee River July Run is a popular fixture in the PHOENIX Running calendar.
