““For me, UltraSwim 33.3 combines three things endurance athletes love: beautiful locations, a real journey from start to finish, and a welcoming community. It’s challenging, but it’s also surprisingly accessible, even if swimming wasn’t your first sport.”

— Tom Jenkinson, Envol Swimrun

Swimming an UltraSwim 33.3 is a test of endurance, not just your swimming technique, speed or style. With point to point swims in breathtaking locations, It’s an adventure rather than a race.

At UltraSwim 33.3, we have athletes from all different backgrounds, some professional swimmers, some who have never swam more than 2km in open water before and everything in between.

Hear from our affiliate coach Tom Jenkinson about his UltraSwim 33.3 experience:

“What surprised me most about UltraSwim 33.3 is that it feels far more like an endurance adventure than a swimming race. You’re moving point to point through incredible locations, managing yourself for hours, and sharing the experience with a really supportive community. I came to swimming later in life, but the skills that matter most here are the ones endurance athletes already have: patience, pacing, and mindset. That’s what makes it so appealing.”

“One of the biggest misconceptions is that UltraSwim is only for lifelong swimmers. It really isn’t. If you’re an endurance athlete, you already understand pacing, fueling, and staying mentally steady for a long day. The water is just the environment. The combination of stunning venues, point-to-point routes, and a welcoming community makes it an experience that’s accessible in a way people don’t expect.”

“For me, UltraSwim 33.3 combines three things endurance athletes love: beautiful locations, a real journey from start to finish, and a welcoming community. It’s challenging, but it’s also surprisingly accessible, even if swimming wasn’t your first sport. That combination is rare, and it’s what makes the experience so memorable.”

“For endurance athletes, UltraSwim 33.3 taps into the same curiosity that draws people to ultramarathons or long swimruns: what happens if I just keep going? You don’t need perfect technique, you need patience, pacing, and the willingness to explore your limits in an amazing environment. The adventure element makes it very special.”

“I came to swimming later in life, after years in other endurance sports, so I still remember standing on the start line of my first UltraSwim wondering if I really belonged there. But once we started moving, it became something different. It felt like a journey, point to point through an incredible landscape, with a community around you that genuinely wants you to succeed. Somewhere along the way, the doubt disappears and you realise you’re capable of far more than you thought. That’s what makes UltraSwim 33.3 so special.”
