The Thames Ring 250 is a tough non stop           trail race over 250miles

The Thames Ring 250 is a 250mile trail race starting in Streatley-on-Thames and following the route on the map in a anti-clockwise direction. The route is mainly on canal and riverside paths and relatively flat.

Runners have 100 hours  (4 days 4 hours) to complete the run, navigating using maps and being supported by checkpoints every 25 miles or so.

Its an extremely tough run testing runners endurance to the limit along with long hours with little sleep and long dark nights.


The race first ran in 2009 and is the brainchild of Anthony Taylor and Dick Kearn and the Trail Running Association.

The race only runs every 2 years and has run 4 times now with an average 30-40% finish rate over the years, this is despite the calibre of experienced runner that step onto the start line.
