What makes a triathlete?

What makes a triathlete?

Eight athletes. Every distance, every level, every reason for joining our sport. SLS3 digs into the motivations and challenges behind what makes a triathlete.

01 / THE CAMPAIGN

A QUESTION WE'VE BEEN ASKING OURSELVES FOR TWENTY YEARS

Is it the 5am alarm? Overcoming nerves on the start line? The discipline to train when nobody's watching? (Who are we kidding - that's what Strava is for) Or the comeback after a tough race?

To find out, we brought together eight athletes from across the sport - from first timers to international age-group champions. What we found was that it isn't a podium or a personal best that defines a triathlete - it's a shared mindset of grit, curiosity and commitment that keeps them coming back to the start line.

Each athlete tells their story below. Watch them in any order.

Then decide what makes yours.
