The Crossing

Greenland. 553km. 28 Days. Done.

In May 2026, I completed an unsupported crossing of the Greenland Ice Sheet. From Point 660 on the west coast to Isortoq on the east. 553km. 28 days on the ice. A sled that started at over 100kg. 9.6kg of body weight lost. Sub-zero temperatures, whiteout conditions, and long stretches of deep, heavy snow. One of fewer than 5 South Africans to have ever completed this. This page is the full story: the data, the updates from the field, and what the ice actually taught me.

This was an unsupported team crossing. Steven, Mardi, Gal, David, Kanch, Mika, Mike, Anna, Knut-Eric and I each signed up individually and completed our own journey. Nobody pulled anyone across. That's what unsupported means.

Greenland Ice Sheet
553 KM Distance crossed Kangerlussuaq to Isortoq. West to east.
28 DAYS On the ice No resupply. No support. No way out.
9.6 KG Body weight lost Mostly muscle. The ice takes what it wants.
2,501 M Highest point Summit plateau. Wind. White. Nothing else.
97,800 KCAL Activity calories Against an intake of ~5,500 a day. Every day.
49% Avg recovery score Operating at half capacity. Every day. For a month.

This crossing was real. The deadline was real. The financial commitment was real. I committed my share. Then the community showed up. People donated to help make this happen. That's not funding. That's belief.

In a world of polished content and curated lives, I did something different. Lived the lessons I teach. In real time. Uncomfortable, terrified, and committed anyway. At 50.

Every story, every failure, every moment of doubt overcome is now teaching material. Real. Lived. Not theoretical. That's what makes this more than a trip. It's the chapter that feeds everything else I build.

"Hard things done properly don't show you something new. They show you how much more of what's already there you haven't touched yet."

"Coming home felt like walking out of a silent room into a party nobody warned you about. The world just carried on. Something in me hadn't caught up yet."

"I saw you speak years ago at a Samy's Camera event in LA when I was just getting started on my photography journey. I have followed you ever since. Every single thing you've written from a coaching perspective resonates with me. You have a gift. Godspeed."

— Craig Elson

"Backing a buddy to do hard things, to ask of yourself questions most never dare to face, to go to the edge of resilience and grit not just to find answers, but to discover the very questions themselves."

The Route

Every camp. Every push day. Every kilometre. Tracked via Garmin inReach Mini 3 Plus.

28 Days of Data.

Every day on the ice tracked using a Whoop 5.0, Garmin Fenix 8, and inReach Mini 3 Plus. Distance, elevation, recovery score, HRV, resting heart rate, blood oxygen, skin temperature, calorie burn, sleep architecture, and cumulative sleep debt. The full picture of what the crossing cost. Including the day the foot gave out, what the post-expedition scans found, and what the body actually did under 28 days of sustained load.

The Day the Foot Went
The numbers show the worst physiological collapse of the crossing. SpO2 at 74.8%. Recovery at 13%. Average heart rate of 124bpm for 11 hours. What the numbers don't show is why.

The foot gave out during the day. Pain accumulated across the skiing hours and by camp that evening weight-bearing was no longer possible. Acute injury on top of altitude, two weeks of caloric deficit, and a body already running on reserves. The data recorded the cost. The reason was a foot that had finally had enough.

The next morning the tent came down and the skiing started again.

What Was Actually Happening to the Foot
The common plantar digital nerve runs between the third and fourth metatarsal heads, at the ball of the foot between those two toes. That nerve is wrapped in a protective sheath called the perineurium. After 30 days in ski boots hauling a loaded sled, that sheath became seriously inflamed on both feet.

The perineurium swelled to 6x normal size on the left foot and 4.5x on the right. That sheath sits in a tight space between the metatarsal heads with nowhere to go. All that swelling compressed directly onto the nerve underneath. Constant pressure. Constant pain. Every single step for the last two weeks of the crossing.

No Morton's neuroma. No fibrous mass formed. Just the sheath, massively inflamed, crushing the nerve from outside. By camp on May 14 weight-bearing on the left foot was no longer possible. The next morning the skiing started again anyway.

Treatment plan: anti-inflammatories, cortisone and steroid injections targeting the sheath directly, with cryotherapy or radiofrequency ablation if needed. Surgery remains on the table if injections don't hold.

May 14. The crash day. Normal SpO2 is 95–100%. Below 90% is classified as hypoxic. Below 80% is a medical emergency in most clinical contexts. On May 14, blood oxygen dropped to 74.8% overnight. After a day of skiing 26.6km at an average heart rate of 124bpm at 2,202m elevation. Four separate days recorded readings below 90%. All while continuing to move.

Expedition Partnerships

Greenland was the first. There is more coming. North Pole. South Pole. A solo Greenland crossing. Other big ice. The brands that come in now get ground-level access: on the ice, in the content, and in front of the audiences this work reaches. Helly Hansen, OM System, Stanley, and Leatherman were part of Greenland. Their gear was in every update, worn in every image, and seen by everyone who followed this crossing. That's what expedition partnership looks like in practice. If your brand wants in on what comes next, this is where it starts.

Greenland Ice Cap Crossing 2026

Svalbard 2013. Where It Started.

The first time I stepped off a plane in Longyearbyen, something about the place pulled me in. I kept coming back. Year after year, hosting small group photo tours for Wild Eye through the Arctic. Svalbard, Greenland, Iceland. Photographing wildlife, landscapes, and places that felt like nowhere else on earth. It's been a love affair ever since, and I still host these tours now. The more time I spent there, the more I learned about its history, the beautiful danger it held, and explorers like Amundsen and the golden age of polar exploration. When I started looking for a white whale experience for my 50th birthday, this is where the whole journey started.

Svalbard 2024. First Steps on Arctic Ice.

Six days at 78 degrees N. First time on polar ice. Hauling sleds through deep snow in temperatures down to -30C. The experience that changed everything and set the course for Greenland. The shadow voices were loud. I outlasted them.

Svalbard 2025. Ten Days at 80 degrees N.

A focused 10-day training expedition. Glacier travel, mountain passes, frozen valleys. Testing every system needed for the crossing. Building polar experience from knowledge into expertise. Eight full days on the ice.

Greenland 2026. The Crossing.

553 kilometres. 28 days. 70 to 100kg sled. Unsupported. On the ice May 1 to May 29. One of fewer than 5 South Africans to complete this. Three years of preparation. Done.

2028. Solo Greenland Crossing.

The Polar Trilogy continues. A solo unsupported crossing of the Greenland Ice Sheet, which would make me the first South African to complete this. Every expedition builds on the last. The planning has already started.

Before the ice, there's the mental preparation. In this conversation with Jacques from The Endure Edge podcast, we talk about the mental preparation and mindset behind the Greenland expedition. The fear. The RAPG framework. What it actually takes to commit to something that terrifies you and then show up for it every day. Worth a watch if you're keen to understand the mindset behind the crossing.

Greenland is the first crossing. Not the last. The Polar Trilogy is on the cards. North Pole. South Pole. A solo Greenland crossing, which would make me the first South African to complete this. Each one builds on the last. Each one feeds new material, new insights, and new stories into the coaching, speaking, and expedition work.

But the ice is just one kind of white whale. I'm open to and actively exploring other adventures that push the same edges. Different environments. Different challenges. Same commitment to doing hard things in real time and bringing the lessons back.

It started on Greenland's ice. That chapter is done. The next one is already in motion.

The Polar Primer is the first on-ramp. Eight days in Svalbard, March 2027, for people who want to know what the ice feels like and do the work on their own resilience while they're at it.

Want to Know What an Arctic Expedition Feels Like? And Work on Your Resilience While You're at It.

If you've been following the Greenland journey and wondering what it actually feels like to be on the ice, this is your way in. No Arctic experience needed. Professional polar guides. A small group. March 2027. Svalbard, Norway. You will need a reasonable level of physical fitness, but that's part of the process. I'll coach you through the preparation personally so you arrive ready.

Two days in Longyearbyen working on resilience, headspace, and performance. Five days on the ice. Skiing, sled hauling, and camping in real polar conditions. One day to debrief and process what you just experienced. Eight days total.

Polar Primer Svalbard
Svalbard, Norway. 25 March to 2 April 2027.

Eight days on and around the ice. Resilience coaching. Real polar expedition. No experience needed. You will need to train and prepare, and I will guide you through every step of that. What I can tell you is this: you will come back a different person. More info to follow 2027.
