The Offas Dyke footpath is is a 182 miles, and is a cherished National Trail. Offas Dyke is an earthwork defence built by King Offa of Mercia in 780AD. It separated Mercia and Powys (to some extent what are England and Wales today). The race is a few miles longer, due to lead in and out of some checkpoint locations, so stands at 185 miles. A shorter 100 mile route is also available.

King Offa's Dyke Race routes

The route passes through the Wye Valley AONB (Area of Outstanding Natural Beauty), then climbs the Black Mountain skirting the edge of the Brecon Beacons National Park, passes through the Shropshire Hills AONB and finally the Clwyidian Range and Dee Valley AONB. The scenery is outstanding, but hand in hand with that, the relentless hills are very demanding.
