One Water Race 2025
August 19-21
The ultimate proof of human capacity
ONE WATER RACE is one of the world’s toughest endurance races, where professional athletes push their limits in an extreme challenge through the world’s largest archipelago and 30.000 islands in Stockholm, Sweden. Teams of three athletes and one support crew race from Arholma in the north to Landsort in the south – 250 km and a distance of 6 marathons – by swimming, running and orienteering non-stop.

About the Race
The concept is straight forward: the race begins at Arholma in the north, and the first to reach Landsort in the south is crowned the winner. Running and swimming are the only means of movement, with no set course – participants can choose their own route. However, they must pass through several undisclosed checkpoints along the way. Navigation and orienteering are crucial, and with a new route each year, planning in advance is impossible.
