In Kairacross Vätsäri, you hike and paddle far into the wilderness beyond pathless trails.
Good orienteering skills are needed to enable the team to progress from one obstacle to the next along a route of their own choosing. Packrafting is needed constantly during the journey, with the fastest route sometimes crossing lakes or rivers, sometimes several kilometres.
The race lasts 100 hours. How far you can go in the time limit depends on whether you are in a strict competitive spirit or whether you choose to go into the wilderness with a relaxed camping attitude.
