About Llandudno Triathlon & Duathlon

Llandudno Triathlon & Duathlon The Llandudno Triathlon & Duathlon on 4 October 2025, based from the holiday town of Llandudno, explores a beautiful part of the Welsh coastline. Distances include a Sprint and Standard Triathlon and a Standard Duathlon (run, bike, run). The triathlons can be entered as a relay in teams of 2-3. Set when the Irish Sea is at its warmest, it's a great time to challenge yourself. The course sees athletes swimming under the iconic Victorian Pier (perfect for spectators), before the bike leg along a closed-road route around Marine Drive, the scenic road leading you around Llandudno's Great Orme. The run leg is along the Promenade, providing a great atmosphere with spectators lining the route for support right through to the finish line. Duathlon Triathlon (Sea Swim + Bike + Run): Solo/Relay Sprint: 750m + 17.5K + 5K Standard: 1500m + 34.75K + 9.4K
