Jönköping Swimrun, which has been arranged for a couple of years, assumes that the participants both run and swim alternately without stopping between the distances. The competition has two main distances, 35 and 15 kilometers respectively. It is the longer distances that, from next year, will qualify for the "Island to Island" - the sport's world championship.

Relatively new sport

The first swimrun competition was held in the Stockholm archipelago in 2006. The sport came after a bet between two brothers three years earlier.

Jönköping swimrun will take place between the fifth and sixth of June next year. Start and finish are located at Rådhusparken in central Jönköping. In between, participants run through residential areas, forests and swimming in Vättern, Rocksjön and Munksjön.
