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 learnt 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 kilometres 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 what she experienced:
Deniz Kayadelen – What Gibraltar taught me about trust, teamwork and true achievement
For ten days, I did nothing. And it was the hardest thing I have ever done.
Not the swimming. The waiting.
I had come to Tarifa to cross the Strait of Gibraltar – that narrow stretch of water where the Atlantic flows into the Mediterranean, where Europe and Africa are only about 14 kilometres 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: around 15.8 kilometres 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 the Strait of Gibraltar whenever you want. The sea decides. The wind decides. The currents decide. You can train for years, organise everything, arrive ready – and then you sit 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 nobody sees
I’m a swimmer, yes. But I’m also a mother. I arrived in Gibraltar, still breastfeeding, with my sleep disrupted, and having trained far less than I would have liked. I’d cancelled major speaking engagements to be here. I’d secured the funding, coordinated with my sponsor, organised childcare, family and work – built an entire structure around a swim that might simply not happen.
And so the questions came, every single day. Will the sea open up? What will my sponsor think if I come home empty-handed? What if I never get another chance? Was all of this – the planning, the cancelled projects, the costs – worth it?
You can’t pretend these ten days are a holiday. Your body is on the shore, but your mind is already in the water. You can’t switch it off, and you can’t really find peace.
What Gibraltar demanded of me during those ten days was not physical at all. It was spiritual. It demanded that I remain calm in the midst of uncertainty. That I have faith. That I accept a truth 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 whole 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 work hard for that promotion. You do everything right. And then you’re told: wait. The economy, politics, the timing – none of it is in your hands. Some lose themselves in this waiting. They get frustrated, they disappear, they walk away to seek an easier challenge. And some stay. They accept it. They keep believing, keep working, keep their faith – and it is usually precisely those people who are still standing when the door finally opens.
On the tenth day, the sea said yes.
Four swimmers, one rhythm
There is something people misunderstand about a swim like this. It looks like an individual achievement. It isn’t.
We were a team of four. And the rule is unyielding: we start together, we swim in sync, we finish together. Break the rhythm, and the whole team is disqualified.
I’d only met these people a few days earlier. Four strangers, four statements of personal goals, suddenly required to trust one another completely, in the most demanding environment imaginable. No time to build trust gradually. No room for ego. No place for subtle mistrust.
Does that sound familiar? That’s exactly how the real world of work operates. 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, at the highest level.
The water taught me two things that I now take 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 pillar – mentally, emotionally, physically, 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 completely.
After two and a half, three hours, I hit the wall – the real one, the inner one. My carbohydrate reserves were depleted. My body switched to burning fat, and during that transition you suddenly feel weak, hollowed out, your motivation seeping away.
And that is the hardest place: the middle. You can no longer see where you started. You cannot yet see where you will end up. You don’t know how much is left, or whether what you carry within you will be enough. There is only the next stroke. And the next. And the next.
Right there, in that deepest moment, something extraordinary happened.
A pod of pilot whales came to us.
They swam beneath us, calm and unperturbed, turning to show us their faces. I could hear them. In the middle of the ocean, exhausted and uncertain, this was the gift I received.
And as I watched them, a thought came to me with perfect clarity. These whales, these dolphins – it matters not to them whether these waters are called Moroccan or Spanish. They see no borders. They simply swim in their joy, leaping, fully present, fully at one with their world.
We, too, are one. On a planet so full of division and conflict, these whales showed me the truth that nature has never forgotten. In the sea, there are no borders. The lines are ours. We have drawn them.
That is why I swam from Gibraltar for world peace. It is my mission. A crossing from one continent to another, through water that belongs to no one and to everyone, is the clearest message I know: the divisions are man-made – and what is man-made can also be unlearned. I carried that – and the whales – all the way towards the finish line.
The Reality of Performance
We arrived after four hours and forty-one minutes. But the honest version of this story is a bit more sobering.
During the swim, our pace fell apart. Some of the team couldn’t keep up with the rhythm the crossing demanded. We swam back, we waited, we tried – for almost 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 taken out of the water so that the rest of the team could complete the crossing.
It was painful to watch. There is no version of that moment that feels good.
But here is the lesson, which I won’t sugar-coat because it is real. In open water, as in business, you cannot fake performance for long. Standards exist for a reason. If the agreed pace isn’t maintained, there are consequences – not out of harshness, but because the goal itself demands it. A team cannot endlessly prop up what isn’t working. Pretending otherwise protects no one. It merely ensures that everyone fails together rather than individually.
That’s not a comfortable truth. But it was never about comfort. There’s a reason why everything I do goes by the name ‘Out of Comfort Zone’.
One final 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 was no real choice: wait until it had passed, or swim around it and add more than two kilometres to a route that had already demanded everything of us.
So we waited. Again. Treading water 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 end, even metres from your destination, you cannot force the outcome. You hold your position. You stay calm. You let what is greater than you pass by – and then you arrive.
The invisible team
We arrived. And on the other shore, in Tangier, my mother and my baby were waiting for me.
I have no words big enough for this moment. Ten days of uncertainty, four hours and forty-one minutes of cold and doubt and grace – and then fulfilment. Complete. With Gibraltar, I had crossed my fourth of the seven channels of the Oceans Seven.
And as I stood there on the bank, the feeling that welled up inside me wasn’t pride. It was gratitude.
Because the story I’ve 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 never demanded that I be certain before he was.
My mental coach, who helped me build inner walls strong enough to hold me up 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 travelled with me into waters they would never see.
No summit is ever reached alone.
Behind every visible achievement are people who hold 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 you all with me across. I am deeply, utterly grateful.
What are you waiting for?
Gibraltar has given me something back that I’d like to pass on to you.
It 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 not in your hands. It is the courage to achieve with people before you know them fully. It is the honesty to face up to what isn’t working. And it is the presence to recognise 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 trust – and where more honesty? How will you reach your own summit and help your team find theirs, in true flow?
If these questions strike a chord with you – and you want your people to ask them too – then let’s talk.»
