Race distances

Experience Races

The EXPERIENCE races are short, fun, entry-level swimrun experiences for anyone.

These races are between 5-7 km long. The courses are fun with easy swims and easy runs. The EXPERIENCE races are for those completely new to the sport or those wanting a pleasant experience.

There are no cut-offs in the EXPERIENCE races.

Sprint Races

The word SPRINT eludes to the distance compared to a WORLD SERIES race, not necessarily to the speed.

These races are between 15-17 km long. They are designed to be fun and challenging in similar terrain as the WORLD SERIES races but with less exposed swims. This is where beginners and top racers meet.

There is usually one cut-off early on in the race.

World Series Races

These races serve as qualifiers to ÖTILLÖ, THE SWIMRUN WORLD CHAMPIONSHIP and also as the ultimate regional swimrun challenge.

The races are long and hard where you can expect to be out anywhere from 5-9 hours.
You need to be prepared for real open-water swims and for some sections of challenging trail-running.

These races have several cut-offs.
