Runn, Natural ice skating destination in Dalarna, Sweden

Runn is a large lake situated between Falun and Borlänge in central Sweden, featuring numerous islands scattered across its surface. The waterway has variable depths and creates different landscapes depending on the season and weather conditions.

The lake has functioned as a transportation corridor for local communities since the early 18th century. Its role gradually shifted from essential travel route to a valued recreation area as surrounding settlements developed and expanded.

Every February, Runn Winter Week (formerly Runndagarna) brings events to the whole lake. Its best-attended item is the Marathon Speed Skating race, watched by millions of television viewers in the Netherlands. The lake also carries a literary memory: in the tale of Gustav Vasa's adventures, the future king crosses Runn to escape Danish soldiers.

In winter, over 30 km of skating trails are plowed on the ice, and Runn Winter Week in February brings marathon speed skating races. Check ice conditions locally before setting out, since thickness varies with weather and snowfall. In summer the lake is used for recreational boating among its many islands.
