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 will continue the festival theme with live music, a climbing wall, children’s inflatables, yoga 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.

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.

All Castle Triathlon Series races will feature a bumper event village offering the latest triathlon wares,  Castle Triathlon branded gear.
