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.

Common questions

How does my activity actually count?

Connect your activity tracker to Route Rally and every kilometre you log adds up automatically. Your marker moves along the route as new activities sync, with nothing to upload and nothing to enter by hand.

Do I have to live near the route?

Not at all. Walk, run or ride wherever you usually train. The route is a virtual target, so your local roads, trails and weekend hikes all push you further along the border.

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. You set the end date when you create the rally, so the pace is yours.
