The MTC Thames Challenge

The MTC Thames Challenge is a demanding four-day ultra marathon covering 184 miles along England’s longest river path, the Thames. Starting from the river’s source in the Cotswolds and finishing at the Thames Barrier in Greenwich, the event is divided into four stages: the Cotswold Ultra (57 miles), Oxford Ultra (49 miles), Windsor Ultra (47 miles), and Richmond Ultra (33 miles). Participants must be self-sufficient, carrying mandatory gear including maps, compass, and first aid.

Accommodation and meals are provided at designated stops after each day’s race. The challenge offers a unique atmosphere of endurance and camaraderie, with bespoke medals and technical gear awarded to finishers. Visit the organization's website for the most recent information.
