The UK's classic 50 mile ultra 2018 is the 10th Anniversary of this fabulous race and is one not to be missed! A tranquil run along the Thames from Oxford to Henley. Ever changing scenery on the river and Red Kites frequently seen soaring overhead. One of the best way marked routes we have come across. This is great race to prepare for even bigger challenges, using the banks and towpaths of England's largest river as well as footpaths and bridleways we have created an Ultra distance course that will always keep you interested. Well stocked feed stations and enthusiastic support complete what promises to be a great day out.
