The Bastion - Full Iron Distance

Date & Location

Hever, Kent

Organiser’s Description

The 2nd running of this iconic race at the stunning Hever Castle. The Bastion has been designed to offer the ultimate challenge for both newcomers to long-distance triathlon, and experienced long-course hands. It will feature a river and lake swim, hailed as ‘the best open water swim ever experienced’; arguably the toughest long course cycle route on offer in the UK, with 2000m of climbing, up through the High Weald of Kent; a mostly off-road run which circumnavigates the two stunning estates of Hever and Chiddingstone Castle.
