Thames Path Ultra Challenge

Thames Path Challenge, part of Ultra Challenge Series, runs along the Thames Tow Path from Fulham's Bishops Park in west London to Henley-on-Thames. Distances include a full 100 km route (also a 2‑day daylight option), a 72 km 3/4, 50 km halves, and 28/22 km quarters, plus a 25 km Thames Bridges Trek and the Thames Moonlight 10 around the festival weekend. Participants walk, jog, or run through landmarks such as Richmond, Hampton Court, Runnymede, and Windsor to a riverside finish.

Notable features: fully signed routes with GPS tracking, marquee rest stops, abundant catering, medical teams, camping options, and a post-finish celebration with medals and fizz. Ultra March and Solo Challenger options add variety. Visit the organization's website for the most recent information.
