Event overview

The Thames Path Ultra Challenge is scheduled for 12-13 September 2026. The main route follows the Thames towpath from the Putney Bridge / Bishops Park area upstream to Henley-on-Thames. The route passes Richmond, Hampton Court, Runnymede and Windsor and finishes by the river in Henley. The challenge is part of a weekend Thames Path Festival that also includes the Thames Bridges Trek and the Thames Moonlight 10, plus the Henley 10K.

Support, services and entry options

Rest stops are provided about every 12.5 km, with larger "major" stops every ~25 km offering marquee cover, catering, seating, changing rooms, medical and welfare tents. The route is fully signed and supported by an event app with GPS tracking; a timing system scans participants at rest stops. Camping packages are available near the halfway point for the 2-day option. Shuttle buses and transfers are offered to local train stations and key venues. There are entry categories including an Ultra March option for brisk walkers and a Trailblazerz option for faster, time-targeted runners.
