Rowing The Atlantic 2027/28

Easy isn't always better

Four friends, four landlocked eggs, four absolute rowing newbies, four times actually at home in the mountains and the air. That’s mountain to sea. That’s rowing 4,800 km non-stop. From the Canary Islands to the Caribbean. This is The World’s Thoughest Row, the 2027/28 Atlantic crossing.

From the Mountains to the Sea — via the Air: Why?
We’re driven by challenge. We aim to push our limits — mentally, physically, and emotionally.
Whether we’re crossing oceans, scaling rock faces, or conquering icy peaks, what truly matters is experiencing nature in its most raw and awe-inspiring form — and respecting it every step of the way.
For us, crossing the Atlantic is about more than just a journey. It’s about teamwork, laser focus, and the collective drive to surpass our own expectations — together.

Challenge

Nothing worth anything is ever easy

Christopher Columbus relied on his sails. Charles Lindbergh trusted his Wright J-5 engine. But for those in the world’s toughest rowing race, the only power they have is their own muscle. The World’s Toughest Row: 4,800 km from San Sebastián de La Gomera on the Canary Islands to Nelson’s Dockyard in Antigua, Caribbean. Each year, brave individuals from across the globe come together, united by a singular goal: to row themselves, their team, and their boat safely across the vast Atlantic.

Solo, in duos, teams of 4 or 5, the rowers battle the forces of nature, night-time temperatures below freezing, shimmering heat during the day, meter-high waves and gale-force winds. They face physical and mental extremes such as sleep deprivation, a daily consumption of over 5,000 calories, an average of 1.5 million rowing strokes and mental isolation. Always in competition with themselves, the other participants and the world record of 29 days, 14 hours and 34 minutes.

The World’s Thoughest Row demands meticulous, long-term preparation and hard training, putting friendships and endurance to the test. In return, it creates new communities, international cooperation and a unique atmosphere before and during the race.

The race organizers check equipment, are responsible for safety and support the rowers on and off the water. They have high expectations in terms of fitness, financing, medical or basic technical training. Each team raises money for a charitable project of their choice; over 19 million euros have been raised since the race started in 2012.

Sustainability and community form the hull, while fame and glory build the cabins. But it’s cohesion and perseverance that steer the rudder of this life-changing challenge.

The waves are high and the storms fierce — to row safely across the Atlantic, we need your support.

ef has climbed the north face of the Eiger over 40 times, with Sändu also making multiple ascents. This iconic north face rises approximately 1,800 meters.

Boscho and Cello did decades of militia military service with the Swiss special-forces in the Parachute Reconnaissance Company 17(https://17er.ch). Among other things, they were responsible for survival, sniper, mountain and parachute training. In contrast to Boscho, who is still in active military service, Cello retired from military service a few years ago due to his age – but he still has strong ties to Company 17.

Sändu serves as a military pilot with Squadron 8. Formerly a professional pilot, he now fulfills his duties as a militia pilot. Over the course of his career, he has flown various helicopter models and is responsible for survival and mountain training for aspiring military pilots.

Charity

the best is yet to come

We work together with the POLG Foundation and support this valuable charity organization.

PolG disease is a genetic disorder that robs the body’s cells of energy, in turn causing progressive multiple organ dysfunction and failure. One might compare it to having a faulty battery that never fully recharges and is in const state of depletion. The disease is uncommon so no one knows how many patients there are. But PolG research could affect everything from Parkinson’s to cancer.
