More Details
Start by running on the wide stony forest track alongside the beach, where you’ll catch glimpses of the Llyn Peninsula before running out onto Llanddwyn Island. After the island, the trails lead further into the pine forest and onto single-track and sandy running. The course loops around to a final section on the path that forms the border between the forest and the open Newborough Warren, with open views out to sea. A final right turn brings runners onto Traeth Llanddwyn, along the beach and back to where they started and a hero’s welcome from the spectators on the finish line!
