An open-water swim in the spectacular 38 acre Hever Castle Lake and River Eden

An undulating cycle that takes athletes around a circuit through the High Weald of Kent, an Area of Outstanding Natural Beauty, and up to the stunning Ashdown forest for the longer distance races.

The largely off-road run circumnavigates the estate as well as taking runners through land owned by the Bellhurst Nature Conservation Trust (the majority of this section is not on public rights of way), then returning to the award-winning castle grounds before athletes make the dash to the tree-lined finishing chute beside the lake.


Hever Castle witnesses hundreds of hardy triathletes taking on the exciting Gauntlet, a middle-distance race that pushed competitors to their limit via a 1.9km swim, 90km bike ride and 21km run.

If the promise of a cycle up the Burren’s Corkscrew Hill in Ireland, a swim in the iconic Chateau Grand Canal or a half marathon though the historic grounds of Castle Howard whets your appetite, see below for a detailed course description of each of our five Gauntlet races.


If the thought of completing all three disciplines at once is holding you back from signing up to one of triathlon events, then the multisport distances could be perfect for you! Perhaps an injury is preventing you from running, you can’t get your hands on a bike for this summer or the idea of swimming in the lake is just too much. Castle Triathlon Series have created the multisport events to allow the competitors to compete in two disciplines of your choice within the triathlons. The same stunning courses tailored to suit you!

**Our junior event witnesses a 300m lake swim before a challenging but hugely fun off-road 8km cycle around the Castle grounds.

The junior race concludes with a 4km trail run around the castle grounds.


For the tweens out there, the Castle Triathlon Series offers a 200m open-water swim in a calm castle lake, a 4km off-road bike in the castle grounds before a 2km trail run finale.


The shortest event in our celebrated children’s races begins with a 100m open-water swim before a 4km bike on traffic-free trails around the Castle grounds.

The race climaxes with a 1.3km run, again on a safe off-road course. One parent is allowed in transition with their children to offer some assistance.

Did the Aquabike Sprint in 2019
The weather let the day down. So much water on the ride. Wich turned into mud on the run. This event was an exercise in doing it anyway.
Did the Junior Triathlon (9-10 yrs old) in 2019
My first Triathlon happened here and it was a great choice although the entry is a bit pricey and the medal is not the nicest one (quite small) unless you pre-order a personalised one which I am waiting for. I had sprint (750/20/5) but have done over 28k in total as transitions were a bit longer. Swimming part - I stayed way too back as a beginner which turned out to be mistake get with others just stay few metres behind, not too far. Water was cold for me but that was because I didn’t have the proper wetsuit. It was easy to follow with enough marshals on kayaks around.The beginning of the cycling course does not start on the road but a muddy/small rocks pathway thus it was a bit difficult but it’s its ashort phase.. The cycling road was surprisingly hilly and there was no traffic closure so sometimes it was a bit challenging with cars queues behind slower cyclists. Passing sometimes difficult due to traffic and narrow countryside roads but lovely sceneries. Run was in laps (2X2.5km) it was definitely trail so pick the right shoes. Overall great experience, however, if you are looking for a Triathlon to make PBs - this one is way too hilly. I recommend for beginners as I found it as a great choice. Enjoy!
Did the Aquathlon Sprint in 2015
This was my first ever triathlon, and it was such a good one to do! The swim is good for people who are bad at sighting (like me), because you always stay around the edge of the lake, and pass through some narrow areas which help you swim in a straight line. The cycle route is a bit rolling and really beautiful, and the run is green and nice.
Did the Sprint Triathlon in 2017
Lovely course, great atmosphere and feels really busy. Great post race experience/village as well...
