Most Atlantic rowing crossings take between 30 and 60 days, with an average around 46 days at sea. The exact duration depends heavily on crew size, route, weather conditions, and experience level. A 14-person crew holds the fastest time ever at just over 33 days, while solo rowers have spent upward of 90 days on the water.
Typical Crossing Times by Crew Size
The most common Atlantic rowing route runs east to west, from the Canary Islands off the coast of Africa to the Caribbean, a distance of roughly 3,000 miles. This “Trade Winds” route takes advantage of prevailing winds and currents that push boats westward, making it significantly more manageable than rowing against them.
Four-person crews are the fastest common configuration. In the 2025 World’s Toughest Row, the annual race across this route, the winning team of five finished in 31 days and 8 hours. The median finisher among 41 boats came in at about 42 days, and the slowest crew took 59 days. That spread gives a realistic picture of what most teams experience. Pairs tend to be slightly slower, with competitive duos finishing in the high 30s to low 40s. Solo rowers face the longest crossings because they can only row about 10 hours per day and must handle everything, from navigation to cooking to boat repairs, alone. Solo crossings of 50 to 70 days are common, and some have stretched past 90.
The Fastest Crossings on Record
The all-time fastest Atlantic rowing crossing belongs to La Mondiale, a 14-person British and Irish crew led by Leven Brown. They rowed from Gran Canaria, Spain, to Barbados in 33 days, 7 hours, and 30 minutes, arriving in January 2008. With that many rowers rotating shifts around the clock, the boat never stopped moving.
For smaller crews, the numbers are impressive in a different way. A British pair, Alex Simpson and Jamie Gordon, set the speed record for two-person boats in 2019, averaging 3.3 mph over 38 days on the Trade Winds route. That might sound slow on land, but maintaining that pace 24 hours a day across open ocean is extraordinary. Even a brief stop to fix equipment or ride out a storm can cost hours that are nearly impossible to recover.
Why the Route Matters So Much
Nearly all organized Atlantic crossings follow the Trade Winds route from the Canary Islands to the Caribbean. The trade winds blow steadily from east to west in the tropics, and the North Atlantic Current pushes in the same direction. Rowers on this route get a consistent tailwind and favorable current, which can add 1 to 2 knots of speed without any effort at the oars. That free boost compounds over weeks and can shave days or even weeks off a crossing.
The North Atlantic route, from the U.S. or Canada to the U.K., is a completely different challenge. Rowers face unpredictable weather systems, colder water, busier shipping lanes, and currents that don’t always cooperate. Crossings on this route are far rarer and typically take significantly longer. The handful of people who have completed it often describe conditions that are dramatically more punishing than the Trade Winds crossing.
What a Day Looks Like on the Water
On team boats, the standard schedule is two hours rowing followed by two hours of rest, repeated around the clock for the entire crossing. That means the boat is always moving, day and night, in sunshine and storms. During rest periods, rowers eat, sleep, check navigation, and maintain equipment. Sleep comes in fragmented 90-minute bursts at best, and the cumulative fatigue over 40 or 50 days is one of the biggest challenges of the entire endeavor.
Solo rowers have more flexibility but less margin for error. They typically row 10 or more hours per day, then use a sea anchor (a small underwater parachute) to hold position while they sleep. Even with an anchor, currents and wind can push the boat backward overnight, meaning a solo rower sometimes wakes up further from their destination than when they stopped. That psychological toll, rowing hard all day only to lose miles while sleeping, is one of the reasons solo crossings stretch so much longer.
The Physical Cost of Weeks at Sea
Rowing across the Atlantic burns a staggering number of calories. Solo male rowers expend roughly 6,400 calories per day, while team members burn between 3,200 and 4,300 depending on sex and shift intensity. For context, that solo figure is about three times what an average active person burns in a day.
The problem is that no one can eat enough to keep up. After approximately six weeks at sea, rowers in a study published in Experimental Physiology were eating as much as their bodies could physically process, and it still wasn’t sufficient. Every participant lost about 10% of their body mass over the crossing, averaging around 9.6 kg (21 pounds) for men and 7.2 kg (16 pounds) for women. Much of that loss comes from muscle, not just fat, because the body starts breaking down its own tissue to meet the energy deficit. Rowers arrive at the finish line significantly lighter and weaker than when they started, despite eating constantly.
Preparation Before the Start Line
The crossing itself is only part of the time commitment. Most campaigns take one to two years to pull together, covering fundraising, boat acquisition or construction, equipment outfitting, safety training, and physical conditioning. Ocean rowing boats are specialized vessels, typically 20 to 28 feet long, equipped with solar panels, a watermaker that converts seawater to drinking water, satellite communication, and enough freeze-dried food to last the full crossing plus emergency reserves.
Physical training needs to start well before departure. Rowers need a strong aerobic base to sustain 10 or more hours of daily effort, but they also need upper-body endurance, core stability, and enough muscle mass to buffer against the inevitable weight loss. Many rowers train for six months to a year with a structured program that mimics the sustained, moderate-intensity effort of ocean rowing rather than the high-intensity intervals common in gym-based rowing.
Factors That Speed Up or Slow Down a Crossing
Weather is the single biggest variable. A favorable weather window with consistent trade winds can shave days off a crossing, while storms or periods of dead calm can stall progress entirely. Some crews have reported sitting motionless for 48 hours waiting for wind to return.
Crew size matters for obvious reasons: more rowers mean more hours of continuous rowing. Equipment failures, particularly to the watermaker or rudder, can force lengthy repairs that eat into rowing time. Even the boat’s hull condition plays a role. Marine growth accumulates on the bottom over weeks, gradually increasing drag and slowing the boat. Some crews periodically jump into the ocean to scrape the hull clean, a nerve-wracking task in water thousands of feet deep.
Mental resilience often determines whether a crossing finishes at the fast or slow end of the range. Sleep deprivation, isolation, monotony, and the sheer relentlessness of rowing day after day breaks some crews down. Teams that manage conflict well and maintain consistent rowing schedules tend to finish faster than those that don’t, regardless of physical fitness.
