Hever Castle Festival Of Endurance 2023

July 9 All day



  • 9 July 2023


  • Hever Rd, Hever, Edenbridge TN8 7NG, United Kingdom

Join us for this Festival Of Endurance Event at the historical Hever Castle Kent.

The childhood home of Anne Boleyn, Hever Castle, is a stunning location for a race. Swim from The Loggia with its Nymph’s Fountain inspired by the Trevi Fountain in Rome.

Run through stunning castle grounds and surrounding villages, and cycle through the Ashdown Forest and South Downs.

Throughout the weekend, athletes and spectators will be able to enjoy a fun-packed festival village featuring live music, shopping, food and drink, children’s entertainment, yoga and more.

Our 2022 Festival Of Endurance event was a huge success; we expect 2023 to be even better!


Festival Of Endurance returns in 2023 for a day full of sporting excitement – highlights include our full iron distance, The Bastion and half iron distance, The Gauntlet and our 50 Miler ultra run.

We also have long-distance duathlons, aquathlons, aqua bikes, and running and swimming races.

This year, we have added new distances to the Festival Of Endurance program: 34 Miler Ultra Run, 50 Miler Ultra Run Relay, Marathon Run Relay, 10K Swim Relay and the 5K Swim!

We hope you will be one of the first to participate in these exciting events!


We are delighted to announce that British Triathlon governs this event. If you compete in a triathlon or multisport event, you will need a valid membership of day licence.


We are delighted to have partnered with Macmillan Cancer Support for another year after the success of 2022. They do whatever it takes to give people affected by cancer the support they need. Macmillan is going all out to support people with cancer. But they can’t do it without you.

You can support Macmillan by signing up for a charity place and committing to fundraising or making a donation via the registration form.
