Introduction
Llandudno is the quintessential Welsh seaside town and just like the traditional pier, this triathlon is full of fun with challenging up, speedy down and fast and flat running. The triathlon is a firm favourite with Llandudno visitors, so expect to hear cheers, bells, and your name shouted at every turn!
Overview
From the start line close to the iconic Victorian Pier, your swim will head out into the Irish Sea at the warmest point of the year. Once back on dry land, the bike section will take you around four laps of Marine Drive, circumnavigating the Great Orme, which is 2 miles long, 1 mile wide and rises 207 metres (679 feet) from the sea. The geology, wildlife, archaeology and landscape are of such importance that much of the headland has been designated a Special Area of Conservation, a Site of Special Scientific Interest and a Heritage Coast. Once the challenging ups and downs of the Orme are behind you, your run follows the line of the beach, completing three laps along the famous promenade with the lap point next to the popular paddling pool and lifeboat station. Make your way home, cheered on by the supporters for a hero's welcome!
