Hever Castle Triathlon, Swim, Run

Hever, Kent


Castle Triathlon Series has provided covid-19 safety information for this event.

Organiser's Description

The UK’s second biggest triathlon, the World’s largest children’s triathlon and the finale of both the Castle Tri Series and the UK triathlon season. Hever Castle Triathlon has established itself as an essential destination for British and international triathletes, for its picture postcard venue, elite action, age-group choice and festival atmosphere. Put simply, instant classic doesn’t do the Hever Castle Triathlon justice.

The races will again commence with an open-water swim in the spectacular 38 acre Hever Castle Lake and River Eden, transitioning into the undulating cycle that takes athletes around a circuit through the High Weald of Kent, an Area of Outstanding Natural Beauty, and up to the stunning Ashdown forest for the longer distance races. The largely off-road run circumnavigates the estate and award-winning castle grounds before athletes make the dash to the tree-lined finishing chute beside the lake. Distance options, including children's races, also aquathlon, duathlon and aquabike standard and sprint events, plus swim and run events.

In light of the recent government announcement (Monday 22 Feb), we are very encouraged to see a return to organised outdoor sport from March 29. All our 2021 events will fall in line with National Governing Body guidance and we are therefore very confident that we will be able to deliver a safe and successful season of mass participation events. We look forward to kicking off our season with the Cholmondeley Castle Triathlon and Multi-Sport Festival on June 19th/20th.

All competitors will receive a medal

There will also be trophies and prize money for Olympic and Gauntlet categories

Each weekend will feature live music and entertainment, retail outlets and concessions, and a variety of locally-sourced foods and refreshments for competitors and spectators alike.
