About the race

Ö TILL Ö is the original Swimrun race, it is the Swimrun World Championship.

ÖTILLÖ is a unique race in a unique environment. Teams of two race together from island to island (Ö till Ö). The teams swim between the 26 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 course starts by the Seglarhotel in Sandhamn and finishes at Utö Värdshus on Utö. The course passes the big islands of Runmarö, Nämdö and Ornö. The trail-running sections are beautiful. At times the course goes through the forest without a trail, but most of the time the course is on trail or gravelled roads. The open-water swim sections are between 100 and 1790 metres long.

To finish the 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.
