Jessheim Vintermaraton is a road race held in November in Ullensaker, Norway, offering 10 km, half-marathon, and marathon distances. The event began in 1984, with the marathon and half marathon included from its inception.
All three courses are on roads. The 10 km course has 34 metres of elevation gain, the half marathon has 203 metres, and the marathon has 247 metres, indicating the longer races are not entirely flat. A 10 km race was introduced later to attract more recreational runners. Ull/Kisa IL Friidrett is the organizer.
