Trail Race Series
The Thames Ring Series features a primary 250 mile loop starting and finishing in Streatley-on-Thames. The route follows an anti-clockwise direction East along the Thames, moving up the Grand Union Canal, and returning via the Oxford Canal. The terrain consists mainly of rural towpaths and footpaths with some urban sections.
Participants can choose from three available distances:
- 250 miles (The full loop from Streatley-on-Thames)
- 150 miles (From the start to Nether Heyford)
- 100 miles (From Nether Heyford to the finish in Streatley)
The course is relatively flat, following canal and riverside paths. Runners navigate the route using provided maps and GPX files. All participants are equipped with GPS trackers for monitoring and safety.
Checkpoints are located approximately every 25 miles and offer various levels of support. Some indoor checkpoints include changing facilities, toilets, and sleeping areas, while outdoor locations may have sleeping tents. Organizers provide baggage transportation for a drop bag to checkpoints along the route.
The event is open to runners aged 18 and over. No specific qualifying criteria are required for entry. Participants must carry a compulsory kit at all times, including at least one litre of fluids, full waterproofs with taped seams, a head torch with 100 lumens minimum, and a mobile phone.
