The Bastion

The Festival of Endurance - Hever Castle

Date & Location

Hever, Kent

Organiser’s Description

An awesome schedule of events will be taking place at Hever Castle on the Bastion weekend. The Gauntlet half-iron triathlon will now be held bi-annually, giving triathletes the option to race alongside the full iron-distance Bastion competitors. The swim is in the main Hever Castle lake and a tributary of the River Eden; the cycle winds its way through the stunning High Weald of Kent and the Ashdown Forest; the run follows largely off-road tracks and bridle paths between Hever Castle and the historic local village of Chiddingstone. And whilst these hardy triathletes battle their way around this iconic course, a further 3 challenges will be on offer for those looking for an opportunity to ‘go long’ on the sections of the Bastion course: Aquabike Challenge, Aquathlon Challenge, and the Hever Long Swim.
