Deniz Kayadelen between two continents: The sea doesn’t always say yes

Deniz Kayadelen knows what it feels like when everything is ready—and yet the sea still says no.

The Turkish-German open-water swimmer, multiple world champion in ice swimming, and Guinness World Record holder has learned to work WITH uncertainty, not against it. As a business psychologist and author, she translates these experiences into powerful lessons for leaders and teams.

In May 2026, Deniz Kayadelen swam across the Strait of Gibraltar – 15.8 kilometers of open water between Europe and Africa – as a mother, as an athlete, and for world peace. It was her fourth of seven legs of the Oceans Seven. Here, she recounts her experience:

Deniz Kayadelen – What Gibraltar Taught Me About Trust, Teamwork, and True Achievement

For ten days, I didn’t do a thing. And it was the hardest thing I’ve ever done.

Not the swimming. The waiting.

I had come to Tarifa to cross the Strait of Gibraltar—that narrow strait where the Atlantic flows into the Mediterranean, where Europe and Africa are only about 14 kilometers apart, close enough to see one continent from the other. The route runs from Tarifa on the Spanish coast to Tangier on the Moroccan coast: about 15.8 kilometers of open water between two continents. On the map, it looks almost small. In the water, it is anything but. Strong currents, one of the busiest shipping lanes in the world, and waters that make no concessions.

But before all that came the waiting.

You can’t swim across Gibraltar whenever you want. The sea decides. The wind decides. The currents decide. You can train for years, get everything organized, arrive ready—and then you’re sitting on the shore waiting for permission that might never come.

So I waited. Ten days. And I want to be honest about what those ten days really meant, because that’s the part nobody sees.

The part that no one sees

I’m a swimmer, yes. But I’m also a mother. I arrived in Gibraltar while I was still breastfeeding, with my sleep disrupted, and having trained far less than I would have liked. I had turned down major speaking engagements to be here. I had secured the funding, coordinated with my sponsor, and organized childcare, family support, and work – building an entire structure around a swim that might simply not happen.

And so the questions came, day after day. Will the sea open up? What will my sponsor think when I come home empty-handed? What if I never get another chance? Was all of this – the planning, the canceled projects, the costs – worth it?

You can’t pretend these ten days are a vacation. Your body is on the shore, but your mind is already in the water. You can’t switch off, and you can’t really relax.

What Gibraltar demanded of me during those ten days wasn’t physical at all. It was spiritual. It demanded that I remain calm in the midst of uncertainty. To have faith. To accept a truth that I resist just as much as anyone else: I am not in control of everything. I can control my emotions. I can control my actions. That is the entire list. The rest – the sea, the timing, the outcome – was never mine to hold onto.

And I think most of us know that feeling, even if we’ve never seen the Strait of Gibraltar.

You’re working hard toward that promotion. You’re doing everything right. And then you’re told: wait. The economy, politics, timing – none of it is in your hands. Some people lose themselves in this waiting. They get frustrated, they disappear, they leave to seek an easier challenge. And some stay. They accept it. They keep believing, keep working, keep their faith – and those are usually the ones who are still standing when the door finally opens.

On the tenth day, the sea said yes.

Four swimmers, one rhythm

There’s something people misunderstand about a swim like this. It looks like an individual achievement. It isn’t.

There were four of us on the team. And the rule is strict: we start together, we swim in sync, and we finish together. Break the rhythm, and the whole team is disqualified.

I had met these people just a few days earlier. Four strangers, four sets of personal goals, suddenly called upon to trust one another completely, in the most challenging environment imaginable. No time to build trust gradually. No room for ego. No room for even the slightest mistrust.

Does this sound familiar? That’s exactly how the real working world works. You’re placed on a project with people you barely know. Everyone has their own ambitions. And yet you’re expected to deliver – together, immediately, and at the highest level.

Water has taught me two things that I now bring with me into every room where I speak.

A team is only as fast as its slowest member.

And a person is only as strong as their weakest link – mentally, emotionally, physically, and spiritually. You can’t train away a weak inner foundation, and a team can’t swim away a missing piece.

In the middle of the ocean

We set off together from Tarifa. The cold hit us immediately and was intense.

After two and a half or three hours, I hit the wall – the real one, the one inside me. My carbohydrate reserves were depleted. My body switched to burning fat, and during that transition, you suddenly feel weak and drained, and your motivation fades away.

And that is the hardest part: the middle. You can no longer see where you started. You can’t yet see where you’re going. You don’t know how much is left, or whether what you carry within you will be enough. There is only the next step. And the next. And the next.

Right there, in that darkest moment, something extraordinary happened.

A pod of pilot whales came to visit us.

They swam beneath us, calm and unperturbed, turning to show us their faces. I could hear them. Out in the middle of the ocean, exhausted and uncertain, that was the gift I was given.

And as I watched them, a thought struck me with perfect clarity. These whales, these dolphins – it makes no difference to them whether these waters are called Moroccan or Spanish. They see no borders. They simply swim in joy, leaping, fully present, completely at one with their world.

We, too, are one. On a planet so rife with division and conflict, these whales showed me the truth that nature has never forgotten. There are no boundaries in the ocean. The lines are ours. We drew them.

That’s why I swam across the Strait of Gibraltar for world peace. It’s my mission. Swimming from one continent to another, through waters that belong to no one and to everyone, is the clearest message I know: Divisions are human – and what is human can also be unlearned. I carried that – and the whales -with me all the way to the finish line.

The Reality of Performance

We arrived after four hours and forty-one minutes. But the true version of this story involves something more serious.

Our pace fell apart as we swam. Some of the team couldn’t keep up with the rhythm the crossing demanded. We swam back, we waited, we tried – for nearly two hours. And slowly, the truth became undeniable: at this pace, no one would make it. Neither the person struggling nor the rest of us. The current would simply carry us all back.

So the observers made the decision that had to be made. One person was pulled out of the water so that the rest of the team could complete the crossing.

It was painful to watch. There’s no way to look at that moment that feels right.

But here’s the lesson I won’t sugarcoat, because it’s the reality. In open water, as in business, you can’t fake performance for long. Standards exist for a reason. If the agreed-upon pace isn’t maintained, there are consequences – not out of harshness, but because the goal itself demands it. A team can’t endlessly cover for what isn’t working. Pretending otherwise doesn’t protect anyone. It just ensures that everyone fails together instead of failing individually.

That’s not a comfortable truth. But comfort was never the point. There’s a reason everything I do goes by the name Out of Comfort Zone.

One last test, just before reaching the shore

The sea wasn’t done with us yet.

Gibraltar is one of the busiest shipping lanes in the world, and as we approached the Moroccan coast, a tanker stood between us and the finish line. We had a choice that wasn’t really a choice: wait for it to pass, or sail around it and add more than two kilometers to a route that had already pushed us to our limits.

So we waited. Again. Wading in the open sea, so close to Tangier that we could feel it – and yet called upon to be patient, called upon to bow to forces far greater than ourselves.

It was the whole journey in miniature. Even at the very end, even just a few feet from your destination, you can’t force the outcome. You hold your ground. You stay calm. You let what’s bigger than you pass you by – and then you arrive.

The Invisible Team

We arrived. And on the other side, in Tangier, my mother and my baby were waiting for me.

I have no words grand enough to describe this moment. Ten days of uncertainty, four hours and forty-one minutes of cold, doubt, and grace – and then fulfillment. Complete. With Gibraltar, I had crossed the fourth of the seven channels of the Oceans Seven.

And as I stood on that shore, the feeling that welled up inside me wasn’t pride. It was gratitude.

Because the story I told you still isn’t the whole truth. You saw four swimmers in the water. You didn’t see the invisible team behind me – and there’s always an invisible team.

My sponsor, who believed in this mission when there was nothing to show for it yet, who believed in me through every single crossing, and who never demanded that I be safe before he was.

My mental coach, who helped me build inner walls strong enough to keep me afloat in the middle of the ocean. My spiritual coach, who taught me to stay present and let go when uncertainty was all I had. And my friends, whose messages and silent wishes traveled with me into waters they would never see.

No summit is ever reached alone.

Behind every visible achievement are the people who hold onto the parts of you that the world never sees. So this is my thank you – to my sponsor, to my coaches, to my family, to my friends. I carried all of you with me. I am deeply, utterly grateful.

What are you waiting for?

Gibraltar has given me something that I’d like to share with you.

This was never just a physical challenge. My mental, emotional, and spiritual resilience were tested far more than my body ever was. True achievement – the kind that lasts – is never one-dimensional. It is the confidence to keep going when the outcome is out of your hands. It is the courage to work with people before you fully know them. It is the honesty to face what isn’t working. And it is the presence to recognize the magic when it appears – even in your darkest moment.

So let me ask you the question that the strait asked me:

What is your goal? What are you waiting for? Where do you need more confidence – and where do you need more honesty? How will you reach your own peak and help your team find theirs, in a state of true flow?
