Adventure Series Triathlon 2024

The Adventure Series consists of three stunning and unforgettable mixed terrain triathlons; The Slateman, The Snowman and The Sandman. Completing the series is a tick that every triathlete wants and a once-in-a-lifetime experience.

As if that wasn't enough, by entering the Adventure Series you receive 50% off the individual event price of the Sandman*

Over the years we've seen an amazing array of athletes enter the Adventure Series from novice to elite. When half the challenge is just in completing all the events, anyone can win and we've had some very surprised champions pick up the exceptional prize packages in the past!

*You will not receive the discount or be entered into the Series if you make separate entries into the individual events. If you have already entered an event and wish to upgrade please contact us.
