Jessheim Vintermaraton is a November road race held in Jessheim, Norway, offering marathon, half marathon, and 10 km distances. The event began in 1984, with the full and half marathons included from its inception. The 10 km distance was introduced later to accommodate more recreational runners. Ull/Kisa IL Friidrett organizes the race.
The routes are not mountainous, but they do include some elevation changes. The 10 km course has an elevation gain of 34 meters, the half marathon 203 meters, and the marathon 247 meters. The marathon and half marathon share parts of the course simultaneously. They converge near the entrance to Myrvegen, where a merging lane exceeding one kilometer allows runners to establish their positions. Staggered start times are used to minimize traffic light disruptions for large groups, and pacemakers are provided for those targeting specific finish times.
