Each year, a few dozen rowing teams set off from the Canary Islands and cross the Atlantic without an engine or sail. Rowing 3,000 miles (4,800 km) to Antigua, they’ll spend months battling waves, weather and themselves while pulling at the oars in 2 hour shifts. It isn’t so much a race as it is a group challenge – the spirit is one of mutual cooperation where boats with 1-4 crew members set off cross an ocean. It’s called the world’s toughest row and perhaps most surprisingly, most teams actually finish. Of the last 38 to set off, 37 have reached the finish. The next race kicks off December 12 and as the date gets closer, you can follow the race tracker on the challenge website.
