About The Bastion
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 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.
The Bastion is an exciting and busy event with lots of different courses taking place throughout the day. There will be a full brief the day before your race but it’s a good idea to familiarise yourself with the course and in particular any key junctions to ensure you take the correct route.
