Adventure Championships Duathlon 2021

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

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

Over the years we've seen an amazing array of athletes entered in to the Adventure Championships 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 in to the Championships if you make separate entries in to the individual events. If you have already entered an event and wish to upgrade please contact us.
