Take in the spectacular Clwydian Range of North Wales with the Excalibur race. The event returns for the fifth time with marathon, half marathon and now 10k options. The marathon course traverses this incredible ridge of hills, following a long, tricky route with more than 1600m ascent. The half marathon takes you through the beautiful Clwyd Forest and up gentle (but high) peaks including Moel Famau, the highest peak in the Clwydian Range, distinctive by its Jubilee Tower.

The very first Excalibur 10k covers similarly stunning scenery and steep inclines. Excalibur raises money for local children’s hospice, Claire House, which cares for children and young adults who will not live to adulthood. If that doesn’t persuade you to sign up, there’ll be steaming pots of hot stew on the finish line for every participant and a bar selling specially-brewed Excalibur Ale.
