We are proud to announce the Garden of Wales Duathlon, the finale of our Spring Duathlon Series, hosted within the spectacular grounds of the National Botanic Garden of Wales.
Set in the heart of the Carmarthenshire countryside, this unique duathlon combines off road trail running through landscaped grounds and natural terrain, with road cycling on quiet, scenic rural roads surrounding the estate. The venue offers a rare blend of sporting challenge and natural beauty, making it a fitting stage for the closing event of the series.
The National Botanic Garden of Wales is one of the country’s most iconic outdoor spaces, renowned for its sweeping parkland, wooded valleys, and world class horticultural collections. Athletes will race through an environment where nature, design, and endurance sport meet, delivering a course that is both inspiring and demanding.
We invite athletes of all ages and abilities to join us in May 2026 for a memorable race that celebrates community, challenge, and the landscapes of Wales. We anticipate 150–200 competitors, representing a wide range of experience levels.
Race HQ, transition, and athlete facilities will be centrally located within the National Botanic Garden grounds, providing a safe, accessible, and spectator-friendly hub for the event.
