Triathlon and Multisport Festival, 26-27 September 2026
Join us for the Hever Castle Multisport Weekend to race through the award-winning grounds and surrounding area of the stunning Kent countryside. Pick your discipline – triathlon, duathlon, aquabike, aquathlon, swim and run – and choose a distance. Recruit your friends and celebrate completing your challenge in our festival village.
Venue
The Hever Castle Multisport weekend event in Kent is set within the stunning and historical grounds. The Hever Castle estate offers a wealth of history; most recognisably the home of two of Henry VIII 6 wives. It was the childhood home of Anne Boleyn and one of the homes Anne of Cleaves was given after her divorce.
Throughout the weekend, athletes and spectators will be able to enjoy the award-winning gardens and a fun-packed festival village featuring live music, shopping, food and drink, children’s entertainment, yoga and more.
Races

Our family-friendly multisport event weekend in Kent features triathlon, duathlon, aquabike, aquathlon, Swim Series and Run Series for all ages and abilities. You can also race with a team of friends in one of our relay options!
