Introduction
Llandudno is the quintessential Welsh seaside town and just like the traditional pier, this duathlon is full of fun with challenging up, speedy down and fast and flat running. The event is a firm favourite with Llandudno visitors, so expect to hear cheers, cow bells, and your name shouted at every turn!
This event has been chosen to host the World Standard Distance Duathlon Qualifier.
This will be your chance to prove yourself in the stunning setting of Llandudno and gain your place on the GB Age-Group Team. Athletes must register their intent to qualify for the race by 5pm on the Friday before the qualifying race (26th June).
Overview
From the start line on the iconic Victorian promenade, your first run will see you do two laps of the first run course, before returning to Transition and your bike. Once out of transition, 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 again follows the line of the beach, this time 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!
