Flisa Backyard is a lap race held in Flisa, Innlandet county, Norway. Runners complete laps rather than racing from point to point. The most recent edition took place amid strong winds and rain, making the challenge as much about enduring the weather as it was about covering distance.
The course format is straightforward: run the same lap repeatedly until you decide to stop. Glenn Hjortefot, 45, finished 21 laps at 05:40 on Sunday morning, illustrating how late into the night the event can extend. The race attracted significant local attention, and the difficult conditions affected all participants at the start.
