Garden of Wales Duathlon

Run

Elevation Gain: 90m
Surface: Mixed trail (tarmac paths, compacted gravel, woodland tracks)

A flowing and picturesque trail run set entirely within the grounds of the National Botanic Garden of Wales. Both run legs use the same scenic loop, allowing athletes to become familiar with the terrain while still being challenged by its variety.
Starting close to the transition area, runners head out onto wide, well maintained paths before entering a network of woodland trails that wind through the heart of the estate. The course gently undulates throughout, with short climbs and descents that test rhythm rather than raw power. Underfoot conditions are generally firm, with occasional gravel and natural trail sections adding interest and character.
Midway through the loop, the route drops into a sheltered wooded valley, where runners pass alongside streams and shaded paths, before climbing gradually back toward open
parkland. The latter stages of the course reward effort with sweeping views across the surrounding countryside, offering a real sense of place and immersion in the landscape.

Bike

Elevation Gain: 400m
Surface: 100% road
A scenic and testing road bike course that showcases the rolling countryside surrounding the National Botanic Garden of Wales. Leaving transition, riders quickly move onto quiet rural roads that form a large loop through the Carmarthenshire landscape, offering a rewarding blend of speed, endurance, and sustained climbing.
The opening section features a steady rise as athletes leave the estate, encouraging controlled pacing early on. This is followed by long, flowing stretches of road where riders can settle into rhythm, interspersed with short, sharper climbs that demand good gear choice and focus.
Around the midpoint, the route flattens slightly, allowing for faster riding before the course delivers its most notable climbing in the latter stages. These longer ascents are balanced by smooth descents, where confident bike handling and line choice are rewarded.
