This swimrun competition began officially in 2006.
The total distance for the race is 75km, of which ten are open-water swimming and the remainder is trail running with some sections of forest. The swimming sections range from 100 to 1790m long. The race transitions between swimming and running a total of 52 times.
Safety boats, medical staff and race marshals are in place to guarantee the safety of all participants.
The race starts on the island of Sandhamn at dawn and finishes on Utö at dusk.
