WANT TO JOIN OUR NEXT CAMPAIGN?

Is it the 5:00 a.m. alarms? The fear before your first open-water swim? The discipline to train when no one’s watching? The comeback after a tough race? The years of chasing marginal gains?
Whether you’re lining up for your very first sprint or you’ve lost count of your finishes, we want to hear your story.

We’re looking for triathletes of all levels - first-timers, age-groupers, seasoned competitors - who embody the grit, curiosity, and commitment that define this sport. Because being a triathlete isn’t only about podiums, it’s about the mindset that keeps you showing up.

As part of the campaign, you’ll:

• Be featured in digital and social content.
• Be kitted out in SLS3 for your upcoming training and racing calendar.
• Get early access to new product drops.
• Help shape future product innovations with your product feedback.
