Glommaløpet is a May running event in Sarpsborg, Norway. Its main long race is 10 miles, or about 16.1 km. The route runs from Sarpefossen to Gamlebyen. The program also includes a relay, shorter races, a Mosjonsløp for those who want to run without focusing on time, and children’s races.
The relay starts shortly after the 10-mile race and splits Glommaløpet into ten stages, with legs from 800 meters to 3 km. This allows teams to use both fast short-distance runners and individuals who prefer a longer stretch. The listed surfaces vary between road and gravel. The event is built around local running rather than a single elite race: Fredrikstad IF organizes it, and the distances range from very short kids’ options around 600 to 900 meters up to the full 10-mile course.
