Llandudno Triathlon & Duathlon 2025

Returning for fourth year this event explores the popular holiday town of Llandudno. Taking place in early October, with the Irish Sea retaining its summer warmth, it's a great time to challenge yourself in this beautiful part of the Welsh coastline!

The course sees athletes swimming under the watchful eye of the iconic Victorian pier (perfect for spectators), before taking to your bike along our closed-road route around Marine Drive, the scenic road leading you around Llandudno's Great Orme.

Running along the promenade provides a great atmosphere, with spectators lining the route, providing the same warm Welsh welcome you can expect at all Always Aim High Events, right through to the finish line.
