Superfeet Sandman Triathlon & Duathlon 2025
The final part of the Adventure Series and a fitting close to the most epic multi-terrain, adventure triathlon series in the calendar The Sandman has been described as the most beautiful triathlon in the race calendar.
The race starts and ends in one of Anglesey’s most treasured spots, the incredible Newborough Forest, an exclusive area of 700ha woods adjacent to the world famous Traeth Llanddwyn Beach.
One of the few Triathlons in the calendar with a beach start and sea swim, your supporters can build sandcastles and eat ice cream whilst you race!
