Stunningly scenic riverside races along the Thames Path towpath on an out-and-back route.


All routes are very flat, fast, invitingly 'runnable' and well-marked meaning no navigation required.

The check points are well-stocked and there is excellent support throughout from marshals and medics, with a great atmosphere at the finish line.

An absolute stunning location with great facilities to prepare for a marathon. A very well organised event and a very friendly Race Crew. Thank you for a lovely few hours on the Thames. I shall return. Heather

Beautiful views of the River Thames on an easy to navigate, two lap out and back, flat course. Small, friendly event with plenty of encouragement from the other runners at the turn around points. Well stocked, frequent aid stations. Range of participants from first timers to 100 marathon club runners and suitable for all. Fun, well organised events that I will be sure to run again. Jackie
