About ÖTILLÖ, The swimrun world championship

ÖTILLÖ is the original swimrun race, it is the Swimrun World Championship. To finish the ÖTILLÖ course from dawn to dusk, the competitors must be very fit and they must be very fast in and out of the water as there are 46 transitions. The teams swim between the 24 islands and run over them. The total distance is 75 kilometres of which 10 km are open-water swimming and 65 km are trail-running.

The start at Sandhamn is mythical and the finish at Utö Värdshus on Utö is like coming to Nirvana. There are spectator spots and food stations at some well- known restaurants on the islands along the way. There are safety boats, medical staff and race marshalls on the course to try to guarantee everyones safety.

The Baltic is the life lung of the Stockholm Archipelago, we work with environmental groups to create awareness about the need for a clean Baltic.
