Torpedo SwimRuns are a mixed discipline adventure sport where participants complete a route which requires running, scrambling (climbing) and swimming. A combination of the latter is referred to as a swamble in Torpedo SwimRun lexicon.

The SwimRun movement has its origins in Sweden, which is unsurprising considering the vast archipelagos there, which make for a perfectly blended route of cross country running and parallel swimming venues.

Part aquatic cross-country, part ravine adventuring, SwimRunning is tough. Add in the drag of those shoes, and the swim sections are a lot more challenging than a conventional swimming event.
