Kalmar Backyard Ultra

About this event

The Kalmar Backyard Ultra brings the increasingly popular backyard format to Sweden's east coast. Held at First Camp Stensö in Kalmar, this event follows the simple but brutal premise: complete a lap within the hour, every hour, until only one runner remains standing. The winner isn't the fastest but the last one willing to start another lap. While the format demands serious mental grit and strategic pacing, the event welcomes runners of all backgrounds with a recreational class option and a supportive atmosphere. Every finisher who completes at least one lap earns a medal, making this an accessible entry point into the unique world of backyard ultras.
