This race course will be up to the highest of ÖTILLÖ swimrun standards. It will be hard and magnificent. The World Series course has everything; lots of vertical climbs and descents, lots of swimming, fantastic trailrunning, lots of wild nature, no people and an abundance of fish on the swims. It is hard to say if it is a runners course or if it is a swimmers course, we think it is a swimrunners course. A total of 38 km, with 7 swims of which the longest is 1,600 metres. A total of 7,600 metres of swimming. Do not take the swims lightly. The race starts and finishes in the small town of Two Harbors towards the west end of Catalina Island. We will transport all the racers to Two Harbors with a chartered ferry from Avalon and back. Spectators will be able to get other sea transportation back and forth. The race will start with some running and swimming sections around Two Harbors with a visit to the USC Wrigley Marine Research Centre before going up into the hills towards the West end with breath-taking hills and views. After almost going to the Westernmost tip you will run and swim in and around coves coming all the way back to a finish in Two Harbors on the beach. Along the course we will have cut-off points for those not fast enough to make it before dark. Make sure that you are a strong swimmer and a strong hill runner to be able to enjoy this course and the incredible views. It will be a massive race.
