Björkliden Arctic Mountain Marathon (BAMM) is an annual rigorous two-day competition in mountain orienteering. Each team is composed of two members competing in an exciting, though challenging overnight race through the Swedish mountains. In 2021 BAMM is adding a new class to the competition in, 10, which unique amongst all classes is a single day event. The traditional classes, 30, 50, and 70 continue as two-day orienteering racing with one night in the mountains.
The race will start and finish in Riksgränsen.
