The birthplace and world championship of the newest trend in ultra-racing, Ötillö is a unique race combining 10km of swimming and 65km of running across 26 islands in the Baltic Sea archipelago in Sweden. In pairs, the athletes must maneuver the wet, slippery conditions of the islands which adds difficulty. However, nothing compares to the massive swimming distances and sea swells, which push all of our racers to the edge, leading to an abrupt and heartbreaking end to the race for one team.
