Mjøsen Backyard Race

Mjøsen Backyard Race is a Backyard Ultra held in Sandefjord. Runners complete 6.7 km loops starting from a single point. Each loop begins on the hour, allowing more rest time for faster laps before the next start. The format permits participants to run a single loop, several loops, or aim for the 12-lap goal of 80.4 km. The total elevation gain across all 12 laps is 2,856 meters. This climbing is likened to ascending from the bottom of Lake Mjøsa to the surface six times.
