Our venue for this awesome event will be Box End Park (Bedfordshire, England). Home of the Bedfordshire Triathlon, the World Cup Quadrathlon, and the unique Ropes & Wires competition; Box End is considered the place to water ski, cable tow, wakeboard, and even has its own Aqua Park. The park runs its own Off-Road Triathlon and Aquathlon Series, holds regular open water swimming sessions, and hosts the Galeforce Events and with two stunning, spring-fed lakes. This idyllic venue offers a picturesque setting for our event, with clean clear waters and a flat(ish) course through a range of terrain.

Tri Dog provides a fantastic multisport event for all participants and we encourage novices and experienced competitors to take part in this fun and challenging experience. Whilst our team is passionate about this dog and human triathlon, we also offer categories to suit complete novices to age group champions, plus options for those of you, or your dogs, who don’t fancy the traditional swim, bike, run format!
