Stomperudrittet

Stomperudrittet is a late-summer mountain bike race held at Sørum skole in Sørum, Norway, starting and finishing at the same location. Participants can select from shorter or longer routes. The 26 km courses are available for touring, recreational, and older youth categories, while 14 km options cater to younger riders and recreational participants. Electric bikes are permitted in the recreational classes. The youngest children, including the Knøtterittet group for ages 0-6, can register at the start. The route primarily follows tractor roads through the landscape, interspersed with some sections of regular road. The longer course extends to Nato, whereas the shorter course concludes at Svartputtvegen. Standard mountain bike tires are sufficient, eliminating the need for fatbikes. Sørum IL also utilizes this area for a winter bike race, a measure adopted after the local ski race, Stomperudrennet, faced repeated cancellations due to insufficient snow.
