Offa's 'Orror is a 20k multi-terrain race on and around Offa's Dyke in the beautiful Wye valley, close to the village of Tintern (home of the famous Cistercian Abbey). If you prefer your races to be characterful and challenging then Offa's Orror is for you. It's hilly. It's muddy. It's tough. And it's located in wonderful countryside.
The route is mainly on footpaths and forest trails with around 480m of climbing. There is virtually no tarmac, so off-road shoes of some sort will probably be needed. The course will be well marked and marshalled and there will be 3 drinks stations.
