The concept is straight forward; 30.000 islands, 250 kilometers. Starting at Arholma in the north, the first to reach Landsort in the south is crowned the winner.  Running and swimming the only method of movement. No track and free choice of route, but with some mandatory unknown check points needed to pass along the way. Navigation and orienteering will prove a critical component of the race.
