Klarälvsloppet Run 21k 2026

Klarälvsloppet Run 21k is a fast half marathon in Värmland, Sweden, from Forshaga to Karlstad. The start is at Forshaga Lärcenter, the finish is in Karlstad, and the race uses a 21-kilometer road course on an old railway embankment. It is traffic-free, certified by the Swedish Athletics Federation, and set up without steep climbs, drawing runners seeking a quick, controlled half marathon. The route is a straightforward point-to-point course rather than a city loop, with three aid stations serving water and sports drink. Many entrants aim for personal-best times because the surface is road, the profile is gentle, and cars are kept off the course. After finishing in Karlstad, runners receive fruit and coffee, a simple post-race offering that fits the event's low-fuss character.
