Course Maps

We are delighted to announce that The Bastion full iron-distance triathlon will be back, for the fifth time, on 8th July 2018.

Set within close proximity to London and triathlon’s heartland of the south-east, each leg of The Bastion has been carefully designed to offer the ultimate challenge for both newcomers to long-distance triathlon and experienced long-course hands.

The nurtured exclusive field continues to show loyalty and grit and we look forward to welcoming them back along with new competitors ready to take on the challenge.


Course Details

The Bastion, the final stronghold of a medieval castle, features a 3.8km river and lake swim, a true toughie of a 180km bike course with 3,000m of climbing and a 42.2km run course that takes place largely off-road including running through the grounds of the beautiful Chiddingstone Castle. The event has generated rave reviews, helping grow this event into one of the truly iconic long-distance triathlons in the world.
