Two runners wearing race numbers jump joyfully on a grassy trail surrounded by hills. The woman on the left has her arms raised, and the man on the right holds walking poles and smiles. Bushes and distant fields are in the background.

Organiser's Description

The only way is up with these Half Marathon/Marathon/Ultra distance races along the Offas Dyke footpath!

The new addition - the 'Ultra' finishes at the summit of Cyrn y Brain above the Horseshoe Pass, and is a distance of 33 Miles in length.

Starting at Prestatyn seafront, the National Trail waymarkers are followed up into the hills on the edge of the town and continue in a Southerly direction, with the scenery and terrain becoming more and more beautiful, and challenging as you go! The registration process will require you to choose between 1 of 2 start times for each distance - with those taking more time going off an hour before those who will complete more quickly.
