The home of the polar bear.

North Cape, Norway

2003: (5 km): 1 hr 4 mins

It was the first time I visualised an entire swim from beginning to end. I first saw the North Cape’s spectacular cliffs, which rise straight out of the Arctic Ocean, from a small zodiac with Nick Peterson, my wingman for the world’s most northern swim. I imprinted every crag and every valley so I would know how far I’d progressed, and how far I still had to go, during the swim.

It would be particularly challenging, not just because of 8°C water, but because I was so thin.

We were serving in the British SAS at the time, and could be deployed at any moment to the Middle East. Here’s the problem: I’m training to do one of the coldest swims on the planet, but I’ve got to be lean and fast because at any time I might be running around in the desert. No insulating body fat allowed.

But there was a warm fire waiting for me on the beach when I completed the first ever swim above the Arctic Circle. A herd of a reindeer had gathered there too. It was the beginning of my love affair with Norway.

No matter how much preparation you do, you only know how good your team is when they’re up against it.

Our team for the most northern long-distance swim (79° North) was made up of some South Africans, some Brits, some Norwegians and a Dane, whose job it was to keep an eye out for hungry polar bears.

It was also my first swim with Tim Noakes, and the first time I experienced his professionalism under pressure. We had taken our outfit to another level. (This same core team would go on to face much harsher conditions in Antarctica, the North Pole and Mt Everest.)

Here’s what I remember about this swim: a massive turquoise glacier feeds into the fjord, with ice chunks as big as buildings breaking off and landing in the 3°C water to form floating icebergs. I swam past them with my head in the water and what did I hear? Snap-crackle-pop – like Rice Krispies. It’s the sound of tiny air bubbles being released from the ice – air that was trapped there as much as 3,000 years ago. To swim through this sound, I thought, is to swim in history.

The Inuit have a saying, “You know who your friends are when the ice breaks beneath you.” I don’t have to walk over thin ice to know who my friends are; they all came with me to Verlegenhuken.

It was also the only time I ever had a disagreement with Tim Noakes.
I had just swum the Magdalene Fjord, at 79° North. That was a perfect swim, but 80° sounded even more tantalising. I wanted to do the world’s most northern long-distance swim there.

Verlegenhuken means ‘Point of Desolation’, and it lived up to its name. The weather was miserable, dark and cold. The sleet lashing the black rocks made the prospect of 3°C water even more forbidding.

Tim felt that a second swim in the space of 12 hours was just too much for my body. But I was determined. He also said he’d never ever seen a more inappropriate place to do a long distance swim. I had to agree with him there. So I promised I would get out of the water the minute he asked me to. Thankfully, I managed to complete the kilometre before he did.

Mum was right – this was not a normal thing to do. And standing on the edge of the ice, I realised I had never been more frightened.

Not just because minus 1.7°C was the coldest water any human had ever swum in. Or because the previous day’s test swim had gone horribly wrong. Not because the water was ink black, and it was 4.2 long, cold kilometres to the bottom. Not even because of the polar bears.

Because one shouldn’t be able to swim at the North Pole in the first place.

Two years previously, 23 per cent of the Arctic ice cover had melted. I was swimming to draw the world’s attention to the effect of climate change on the Arctic.

The swim took 18 minutes and 50 seconds. And the combined efforts of a dedicated team that kept hold of the vision. Their motivation turned an impossible kilometre into 10 possible hundred-metre stretches.

Each section represented a nation, and the people who brought me here. Their flags spurred me on.
