3.8km/180.2km/42.2km Following the success of the Gauntlet, which will have over 2000 competitors entering the middle-distance event across the series in this year; the Bastion which take place in July’s mid summer, was a natural progression to feed that hunger for more.
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, will feature 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. Following a huge success in 2014 generating rave reviews, the iron distance men and women enhanced the experience in 2015 contributing to growing 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.
The spectator experience at the Castle Triathlon Series has become almost as famous as the spectacular backdrops and classic courses, and has made passing time before your loved ones finish the race a thing of the past.
