The Thames Challenge Ultra
England's longest river path – from the source of the Thames in the Cotswolds, to the Thames Barrier in Greenwich, a distance of 184 miles. The challenge is to complete the entire length over a four day period. The Thames Challenge is the 'Sister' event of The Severn Challenge. Each daily Ultra - Cotswold Ultra, Oxford Ultra, Windsor Ultra, Richmond Ultra - can be done individually. 8-11 August.
First-hand event reviews from people who've been there, done that and got the breathable T-shirt, really help everyone choose their next event.
It only takes a few seconds and every month we randomly select someone who has taken the time to write a review and send them a £50 Wiggle voucher.
