Open to Offas

Open to Offas is a long-established challenge event located in North East Wales. Based at Cilcain Village Hall in Flintshire, the event offers three distinct distance options for participants:

  • 32 miles (52 km) with 6,377 ft (1,944 m) of elevation gain.
  • 24 miles (40 km) with 4,945 ft (1507 m) of elevation gain.
  • 16 miles (25.5 km) with 2,792 ft (851 m) of elevation gain.

The event is open to both walkers and runners. All routes climb into the Clwydian Hills to follow the Offa's Dyke Path ridge over Moel Famau before returning through woodland and Loggerheads Country Park. The longer distances also extend toward Moel Fenlli and Llanarmon-yn-Ial. The terrain consists of established paths and wooded countryside.

Participants on the 32 mile route must adhere to a cut-off time at the third checkpoint; those arriving after this time will be directed to an alternative route. Entry includes a detailed route description, refreshments at checkpoints and the finish line, and a certificate.

Participants are required to carry a physical or electronic map of the area (Explorer 265 or Landranger 116). Dogs are permitted but must remain on a lead throughout the event and are not allowed inside Cilcain Village Hall. All participants under the age of 18 must be accompanied by an adult. The start location is situated approximately two hours from Birmingham or Leeds. Visit the organization's website for the most recent information.
