Take Part


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.


Each weekend of the 2016 series will continue the festival theme with live bands entertaining the crowds, children’s inflatables, climbing wall and an array of retail outlets and concessions.

The historic Castle grounds are open for exploration, with lakeside walks and nature and wildlife spotting just some of the options for spectators to partake in.

Please note that where a spectator fee applies, all funds raised are taken by the venue and ploughed back into improving the castle grounds specifically for triathletes.

Each Castle Triathlon Series race will offer a variety of locally-sourced foods, with succulent hog roasts and wood fired pizza just two of the highlights, with a huge variety of refreshments for competitors and spectators alike.

What’s more, Vita Coco will be on hand to quench the thirst of competitors with their post-race hydrating coconut water served from a beach hut.

All Castle Triathlon Series races will feature a bumper event village offering the latest triathlon wares,  Castle Triathlon branded gear, Speedo shop, and Kitbrix bags to name a few.
