Meet Krzysztof Gajewski, 34, from Poland. The toughest man in the ICE. On 13 Dec 2025, Krzysztof broke his own WR Ice Swim, swimming 6,025 metres in 4.18°C water in a lake in Poland. 

His Motto is "Discover new lands and sail to the unknown..."

Three months later, he attempted to swim at Nordkapp, the tip of Norway, the northernmost point in Europe, at 71.01 ° North. He set another amazing World Record, the longest Polar Ice Swim, 3.43 km, in just under an hour, at an average water temperature of 3.09 °C. He described swimming in such a remote location at sea, in such a hostile environment, as adding a significant mental challenge.

He also managed to swim 2 km at 0°C in the famous Hintertux Glacier at an altitude of 3250 m in an icy tunnel where the well-known Josef Koberl holds his icy swim camps. 

"The problem isn't hypothermia. Thermally, you're often much better than many athletes who swim a kilometre or five hundred metres. It seems illogical, but the warm-up process after getting out of the water is very short." Krystof, together with Dr Michal, is observing an interesting phenomenon of core body temperature rising after a prolonged ice swim. Whether it's unique to Krzysztof or something we will discover in the future, who knows... still so much to learn about Ice Swimming.  

When we asked him where the limit in distance ice swimming is, he said, "What actually stops a distance ice swimmer is harder to name, and different every time. Sometimes it's a drop in glycogen levels, sometimes cramps, difficulty maintaining a lying position in the water, loss of concentration, balance, or breathing problems. These are at least a few factors that, when combined, determine whether you're able to continue swimming," says Kryztof. "Not hypothermia. A slow, complex convergence of physical systems, each one manageable alone, collectively impossible to ignore."

"This nicely demonstrates how complex and diverse a sport ice swimming is, and how difficult it is to compare individual swims."

"The biggest challenge is always when you're already cold, around 2 kilometres, and you still have a long way to go. I fight the thought that it's impossible to reach my goal. After that, it's easier, because I'm 100% focused on surviving and continuing swimming."

The only objective becomes the next stroke.

Training for this is a balance most people would find contradictory - high body mass for cold endurance, combined with enough speed to actually reach the target distance before the body gives out.

"These are two mutually exclusive parameters. On the one hand, you need to be able to endure long periods of time in cold water. But if you swim too slowly, you won't achieve your goal."

Krzysztof didn't start distance ice swimming for records. He started because he wanted to understand something.

"I've always been curious about the limits of the human body's capabilities, particularly the processes in our bodies that determine how long we can endure cold water. The best way to understand this topic was to test it myself."

After every record, he sits with his team to analyse what could have been done better, what preparation could be improved, and what the data showed. And then the only logical conclusion presents itself again. Go further.

"After such an analysis, the only solution is to test our capabilities again."

Not as dangerous as you think. More remarkable than you can imagine.

The biggest misconception about distance ice swimming, according to Krzysztof, is that it's reckless.

"The process of losing the ability to swim is similar each time and happens very slowly. This allows you to identify a clear point at which to stop swimming without risk."

He doesn't do this alone. He works with one of the world's leading cold-water safety specialists, and every swim is built on preparation, analysis and trust.

This is not a death wish. It is science, discipline and curiosity, pushed to the edge of what a human body can do in water.

Nevertheless, ice swimming is an extreme sport, and long-distance ice swimming can be dangerous. The safest way to practise it is to set safety triggers that, when observed, terminate the swim immediately. It requires experience and an experienced support team.

World Record: 6,025m longest ice swim




What happens when a pool swimmer steps into 4°C water for the first time?

Peter Plavec knows exactly what happens. Because he's been on both sides.

In 2017, Peter couldn't swim. Not properly. He started with cold water dips, just immersion, nothing more. Then he watched the people around him actually swimming in the ice, and something clicked. He got a coach. Learned Breaststroke. Then freestyle. Built his technique from the ground up, in some of the most extreme conditions the sport has to offer.

What he discovered along the way has a message for every pool swimmer watching from the sidelines.

"Pool speed definitely helps in ice swimming. I build my speed and technique in warm water, then apply those same skills in icy conditions. The foundation, technique, pacing, efficiency, still carries over. You just have to overcome the cold."

And the cold, he'll tell you, is real. When your body hits near-freezing water, muscles stiffen, circulation shifts, and strength drops, even for experienced swimmers. Pool training doesn't prepare you for that. But it gives you everything else you need.

"The cold is big, but not the only difference. There's a mental aspect, pacing changes, and you have to manage your body's reaction. That said, pool swimmers have the skills, once they adapt to the cold step by step, they'll find it's a thrilling extension of what they know."

The bridge between pool and ice isn't as long as most people think. The technique is the same. The discipline is the same. The distance is the same. What changes is the environment, and what that environment demands from you mentally.

For Peter, making that crossing didn't just make him a better swimmer. It gave him something else entirely.

"Ice swimming gave me a fantastic community, a lot of fun, and a sense of adventure. It adds something extreme to swimming, making every swim feel like an adventure. That's something pool swimming never gave me."

He started with a dip and a few metres of backstroke.
Now he races on ice.

If you're a pool swimmer, the water is waiting. 🧊

The 7th IISA Ice Swimming World Championship: Oradea, Romania




68°11' South. 1.9°C. Floating ice on the course. Antarctica.

IISA swimmers took on three days of ice swimming at the bottom of the world, from test swims at Horseshoe Island to 1,000m main swims at Stonington Island.

Cari Graf became the first Namibian to swim in Antarctica. Vitalii Kochnev, a para swimmer, covered 900m on upper body strength alone. Toni Enderli headbutted a floating iceberg mid-swim and carried on.

Penguins, whales, leopard seals.

This is ice swimming at its most extreme.

Antarctica Ice Swimming




One swimsuit. Water below 5°C. No wetsuit. No neoprene.

That's ice swimming.

Your body goes into cold shock within seconds. Breathing spikes. Muscles shut down. And you have to override all of it.

An Ice Mile is 1,609m in sub-5°C water, one of the hardest endurance swims on the planet.
You don't get used to the cold. You learn to manage it.

Would you try it?

One swimsuit. Water below 5°C. No wetsuit.




There's No Other Feeling Like Ice Swimming | IISA.

What makes someone willingly enter water below 5°C?

It's not about toughness. It's about what happens when the cold strips everything back: no distractions, no noise, just you and the water.

Ice swimming demands total focus. And in return, it gives you a feeling that nothing else comes close to.
Whether you're an experienced ice miler or you've never heard of the sport before, this is what it looks like.

Swimming in Antarctica | Inside an IISA Ice Swimming Expedition.

Antarctica is the ultimate test for an ice swimmer.

Water temperatures hover around 0°C. The landscape is vast, silent and completely unforgiving. 

Swimmers who make this journey don't do it for the content. They do it because Antarctica represents something bigger, the furthest edge of what the sport can offer.

This is what an Antarctic ice swimming expedition looks like from the inside.
