Why this route

  • Offa's Dyke Path follows the England-Wales border for about 289 km (179 miles) from Prestatyn on the North Wales coast to Chepstow at the mouth of the Wye.
  • As a virtual challenge you cover the distance in your own time, with walks, runs and rides from anywhere counting towards the river estuary finish.
  • The route traces the line of the 8th-century earthwork built by Offa, King of Mercia, as a boundary marker between his kingdom and the Welsh kingdoms to the west.
  • The terrain varies from gentle pastoral valleys to the high ridges of the Black Mountains and the Clwydian Hills, giving the route real variety across its length.
  • Its length suits a multi-month walking goal, where consistent daily or weekly movement builds steadily towards the Severn estuary.

Highlights

  • Start at Prestatyn on the North Wales coast at the northern end of the trail
  • Cross the Clwydian Range, the Dee Valley and the hills of Shropshire
  • Follow the Black Mountains ridge high above the Wye Valley
  • Finish at Chepstow Castle on the Severn estuary at the Welsh border

Common questions

How does my walking count towards Chepstow?

The counting is automatic once your Strava or Apple Health account is linked, and every activity on it moves you south along the border from Prestatyn. A runner at 40 km a week reaches the Severn estuary in around seven weeks, and a walker at 30 km a week in about ten.

Do I have to walk on the England-Wales border?

No. The border sets the distance and leaves the ground entirely to you, so your local roads and hills all move you along it. Offa marked a boundary between two kingdoms; the modern path that traces it runs about 289 km, and covering that length is the whole of the virtual challenge.

What is Offa's Dyke?

Offa's Dyke is an 8th-century earthwork running roughly along the England-Wales border, built on the orders of Offa, King of Mercia. Stretches of the original bank and ditch are still clearly visible along the trail, making it one of the longest surviving early medieval monuments in Britain.

How long does it take to walk?

At 30 km a week it takes roughly ten weeks. Build to 50 km a week and you reach Chepstow in about six weeks. The rally's end date is yours to name at setup.
