About the race

Ö TILL Ö 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 52 transitions.

The Seglarhotel in Sandhamn and Utö Värdshus on Utö guarantee a high quality pre-race scene and a very good finishing environment. 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.

To gain entry to ÖTILLÖ you must either go through our Qualifiers, have great merits or just be lucky.
