The Effortless Swimming Podcast

What would drive someone to voluntarily swim through the most dangerous ocean channels on the planet — no wetsuit, no cage, no way out except forward?

In this episode, we sit down with Mark Sowerby, one of the few athletes in the world to complete the Ocean's Seven — often described as the Everest of open water swimming — a feat achieved by just 36 swimmers.

His new film, Don't Be Prey, captures a decade-long pursuit across five continents and seven of the most brutal channels on Earth. From the freezing Irish Sea to the shark-patrolled waters of Hawaii, it's raw, unfiltered man versus nature — no protection, no shortcuts.

But this isn't just a story about distance or danger.

After a life-changing event leaves him searching for direction, Mark channels his anguish into purpose with the help of coach Tim Denyer. Together, they build a mindset around one simple but powerful mantra: keep the stroke steady, don't splash, keep the heart rate down — don't be prey.

We go beyond the film to explore the swims that nearly broke him, the unseen moments of doubt, and what the ocean taught him about fear, patience, resilience, and staying calm when everything around you is chaos.

This is a conversation about endurance — not just in the water, but in life.

Let's dive in.

There's a timing pattern that separates fast swimmers from slow swimmers—and most people never see it.

You can watch someone swim in real time and miss it completely. But slow the video down, frame by frame, and suddenly it's obvious. Every fast swimmer has this. A lot of slower swimmers don't.

And when you fix this one timing detail, it doesn't just make you smoother—it feels like someone just switched the engine on in your stroke.

In today's episode, I'm going to break down exactly what that timing pattern is, why it matters so much, and most importantly, how you can actually feel it in the water so it shows up in your own swimming.

I watched a swimmer fix one breathing mistake and drop 12 seconds per 100 meters—not in four months, but in four weeks.

No extra fitness. No added training volume. Just one specific change in how she breathed.

That single adjustment took her from 1:48 per 100 down to 1:36 per 100.

In this episode, I break down exactly what she changed, why it worked so fast, and how you can apply the same breathing fix in your very next swim—whether you're training for endurance, speed, or just want to stop feeling rushed every time you turn your head to breathe.

If your breathing feels like the limiter in your freestyle, this episode will change how you swim.

At 20 years old, I missed qualifying for the National Championships by three hundredths of a second in the 50 backstroke. Fast-forward 18 years, and at 38, I qualified for Nationals in the five-kilometer open-water swim—training mostly just three times a week.

In this episode, I'm breaking down exactly how I did it in my late thirties: the one thing an Olympic gold medalist taught me that helped me generate more power with less effort, why getting injured before the race actually worked in my favor, how just five minutes with one coach changed my technique in the final two months, and the single workout I repeated every week that built my endurance and helped me finish fast.
