7 Marathons, 7 Continents, 7 Days: the World Marathon Challenge

The concept is simple; the execution an extraordinary feat of human endurance. Zimbabwean businessman George Economou took up the 2025 World Marathon Challenge, travelling 40 000km around the globe to run 295km in under a week. Moving from frozen tundras to sun-soaked beaches, he faced discomfort, fatigue and self-doubt - and proved that anyone is capable of doing the extraordinary.

I didn’t grow up as a runner. In fact, I only started running later in life, at an age when many people are beginning to slow down. I'd spent years prioritising everything but my own wellbeing, and something had to change. It all started in 1999, when I volunteered to second a friend running the Comrades Marathon. I was so overwhelmed by the spirit of the event, the grit, the emotion, the sheer human effort, that over a beer the next day, I decided to give running a go. At first, it was just short runs to clear my head. Then longer ones to test my limits. I ran my first Comrades in 2000 and the rest is history.

Running gave me structure, purpose and perspective. It became my therapy, my joy and my teacher. I'm happier, more focused and more resilient because of it.

The World Marathon Challenge had been on my radar for years. Seven marathons on seven continents in seven days seemed so outrageous, so impossible - that's what drew me in. I wasn't chasing a record. I was chasing personal growth. I wanted to see if I could do something extraordinary-something that scared me a little. Because I've learned that when something scares you, it's probably worth doing.

NOTHING FULLY PREPARES YOU

Training was relentless. I did back-to-back long runs, heat training, cold training, sleep-deprived runs... everything I could to mimic race conditions. I ran when I didn't feel like it. I ran when I was sore, tired, hungry - because I knew that on race week, I'd have to run through all of that and much more.

But the truth is, nothing fully prepares you for this challenge. You go in with spreadsheets, plans and strategies - but they all go out the window when you're standing on a glacier in Antarctica or boarding your fourth flight in two days with barely any sleep. You learn to adapt. You learn to listen to your body, and sometimes, you learn to ignore it.

What really got me through wasn't fitness, it was mindset. A quiet belief that I'd find a way, one step at a time. That's what makes this more than just a race. It becomes a journey of discovery. Not just around the world but into yourself.

A WHIRL OF CONTRASTS AND CONTROLLED CHAOS

The contrast between continents was staggering. In Antarctica, its cold, you're racing in near silence. In Brazil, its festive, hot and humid. Each location challenged us in different ways-cold, heat, terrain, fatigue. The organisers and crew were fantastic throughout. Aid stations were consistent, with electrolytes, food and medical support at every loop. Everything was well planned.

Logistics is a major part of the race - we travelled 40 000km in under six days, with a few runs in-between.

It's chaos, but controlled chaos. We flew on a private charter, and time in the air was nearly three full days. You try to sleep whenever you can, stretch in aisles and eat when your body says no. We changed into our running gear on each flight, always before landing, always under time pressure. Every leg required precision and planning - you had to be meticulous about what went into your carry-on bag. If you left anything in your checked luggage, you risked being without it on the run.

Clearing immigration at every destination was unpredictable but no one was lost or left behind. It's not an easy feat rounding up over 80 athletes and crew.

Recovery became a top priority. Compression socks, hydration, foam rolling and even micro-naps were survival tactics. You're constantly tired, but the adrenaline somehow carries you. The organisers, the volunteers, locals, fellow runners - they are what made it unforgettable.

RUNNING IS FOR ANYONE WITH A WILLING HEART

So where to next for a guy who's seen and done it all? I get asked that question a lot. I'm not done running just yet. But I do think the next chapter will be about more than just finish lines. I want to help others step into their own adventures. Whether it's through supporting, speaking, or using running as a platform for fundraising, I feel a real pull to give back to the running community that's given me so much.

I also want people to know: you don't have to be the fastest, or have the athletic build of a Usain Bolt or Gerda Steyn, to get out there and experience one of the most rewarding things you can do. Running isn't just for the elites. It's for anyone with a willing heart, a pair of shoes, and a reason to move forward. I am living testament of that.

That said, there are still a few big dreams on the horizon. The North Pole Marathon is definitely calling my name, as is the legendary Sparta Ultra in Greece - a race steeped in history and grit. And then there's one more, perhaps the most meaningful of them all: a celebratory return to the Comrades Marathon, running side by side with my daughter at the 100th edition in 2027. That one will be pure heart.

ANTARCTICA

Quiet, vast and unlike anywhere else on earth. Running in Antarctica felt like stepping onto another planet. The snow and ice underfoot made for a soft, uneven surface - almost like running on sand - and every step required focus. The cold wasn't harsh or biting, but it was ever-present, with sub-zero temperatures and a constant wind reminding you of the remoteness of it all. The landscape was breathtaking with a pristine white canvas stretching out in every direction.

We flew into Antarctica on a specialised cargo plane - loud, basic, upright seats, but no one minded. The thrill of touching down on Antarctic ice erased any thought of discomfort. There was no time to settle in. A quick briefing and we were on the start line. I finished the marathon with just enough time to spare before we were loaded back onto the plane for the six-hour return flight to Cape Town.

That flight back, sleepless and cramped, was a different kind of challenge. Knowing we'd be running again only two hours after landing made the journey feel even longer. But Antarctica had given us something unforgettable, a humbling, majestic beginning to the adventure of a lifetime.

CAPE TOWN

From cold to heat. Cape Town welcomed us with warmth and coastal energy. From early morning it was extremely hot, and keeping hydrated was most important on this leg. There is always something uplifting about running in Cape Town, and South African hospitality always shines.

Locals lined the course with cheers, and early-morning joggers joined in, weaving through the runners with smiles and high-fives. It felt like more than a race, it felt like community.

After the stillness of Antarctica, Cape Town was a joyful contrast, and it gave us the momentum needed. Marathon 2 done - on two continents in just under 24 hours!

PERTH

We managed to get a few hours of rest on the long-haul flight to Western Australia. The heat in Perth was dry and constant. We started running at 9pm under a heavy sky. The race was flawlessly organised, and the course was quiet and free from spectators. There was a calm stillness to this run, a kind of solitude that allowed you to be alone with your thoughts.

For me, this leg also came with a special lift. I had arranged to meet a friend who had moved to Australia several years earlier, and she joined me for the first half of the marathon. Her company brought me comfort and familiarity, a much-needed distraction from the mental and physical fatigue. We were in and out of Australia in under 14 hours.

DUBAI

Arriving in Dubai was like stepping into a world of luxury. We were ushered through the private jet terminal and glided through customs like visiting dignitaries. After the cold and chaos of earlier flights, it felt surreal to be treated with such calm efficiency. The course was laid out in zig-zagging laps around the Dubai Expo Centre.

The weather was pleasant and not as hot as I had anticipated. But Dubai was the wall for me, mentally and physically. I had to dig deep, block out the fatigue, and remind myself why I was here. Crossing the finish line in Dubai wasn't about speed or style. It was about grit. That run broke something in me, and then rebuilt it stronger.

MADRID

A simple yet exciting course with no bustle of people beside spectators at the start, and a time to form lasting friendships with fellow runners. We ran laps around a Formula One track with one or two manageable climbs on each loop. This marathon became one of my favourites.

I found rhythm here. My legs felt stronger, my breathing calmer. By now my body had accepted the new normal: wake, run, travel, repeat. Madrid gave me something I didn't expect, confidence with ever increasing levels of fitness. I no longer questioned whether I could finish. I just ran.

FORTALEZA

The heat was back and with it, the humidity. We started before sunrise and even at that early hour, the Brazilian promenade was alive with movement. Locals, joggers, walkers and competitive runners filled the streets. Every loop brought new faces, new cheers. It was impossible not to feed off that atmosphere.

The camaraderie on this leg was incredible. We passed each other again and again, exchanging expressions of fatigue, pain, cheers, smiles. It was hard, but knowing we had one more to go gave us the endurance to push ahead. We were also under time pressure. The organisers had decided to go for a record and to finish the series in under seven days.

After the race, we barely had time to shower and eat before being whisked onto buses and toward the airport. Miami's race, originally planned for 5am, had been rescheduled for midnight.

MIAMI

The final leg. We started under cover of darkness, running an out-and-back route along Miami's iconic South Beach promenade. A flat 10km loop repeated until we reached the finish. This was it: one last marathon, one last push.

My wife and daughter had flown in the night before to welcome me at the end. Seeing them after everything we'd been through was deeply emotional. Their presence gave me a renewed sense of purpose, a burst of energy that went beyond physical strength. Despite a swollen Achilles and six marathons already behind me, the finish line now felt within reach and that made the pain and fatigue insignificant.

This was my fastest marathon of the series, just over five hours. I crossed the finish line into the welcoming arms of my wife and daughter, in disbelief, pride and joy. Around me, fellow runners were doing the same. Laughing. Crying. Hugging. We had all crossed continents, broken through limits, and arrived at something extraordinary. The clock stopped after the last runners came through. 5 days 16 hours! The record was broken. We had run the world.

7 KEY TAKEAWAYS

Train your mind, not just your legs. Endurance is more mental than you think. You'll run through exhaustion, across time zones, and under different conditions. Your mindset will get you through when your body wants to stop.

Dial in your recovery strategy. Sleep, hydration, nutrition and recovery tools (like compression socks and massage guns) make all the difference. What you do between races is just as important as the races themselves.

Don't experiment on race week. Only bring gear, nutrition, and clothing you've tested extensively. Race week is not the time to try new shoes or trendy gels. Pack light but pack smart.

Connect with your fellow runners. The camaraderie is something special. You bond deeply with people who are going through the same physical and emotional highs and lows. Laugh together. Support each other. You'll make lifelong friends.

Soak it all in. You'll run in some of the most iconic and remote places on earth. Don't rush through it. Look up. Take mental snapshots. Appreciate the privilege of where your feet are taking you.

The experience is bigger than the medals. This isn't just about times or finishes. It's about the moments in-between, the shared meals, the 3am airport walks, the sunsets in faraway places, and the deep, fulfilling satisfaction of doing something truly extraordinary.

It's not just a race - it's a once-in-a-lifetime journey.
