The iconic endurance challenge will kick off with a 3.8km lake swim before a 180km bike takes competitors around the Kent countryside. A 42km marathon run completes what will be arguably Britain’s toughest and most rewarding long-distance event.
We are in complete awe at the performances this weekend, 10th July 2016. A very well done to all our valiant Bastion competitors
We are delighted to announce that The Bastion full iron-distance triathlon will be back, for the fourth time, on 9th July 2017. Registration is now open and for a limited time only, you have the option to gain a special early bird rate and take your place at the stunning and historic venue, Hever Castle in Kent,
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.
