Trondheim - Oslo is a 515 km touring bike race from central Trondheim to Norway's capital, covering 4,220 m of elevation gain on the full route. Riders depart from the town square in Trondheim before dawn, with initial groups starting around 04:00 and the fastest riders dispatched first. It is considered the world's longest and oldest touring bike race, held annually since 1967 except for pandemic cancellations. This is not a short sportive with a city finish; it is an overnight test between two major Norwegian cities.
The route heads south from Trondheim, utilizing eight official aid points before Oslo. These include stops near Soknedal, Oppdal/Fagerhaug, Folldal, Ringebu, Lillehammer, Skreia/Totenvika, Eidsvoll verk, and a final drink station at Frogner. Volunteers from local teams and associations staff the aid stations, offering riders technical assistance alongside neutral service from support vehicles on the road. The finish is in Groruddalen in Oslo, providing riders with a light meal, cafe access, showers, toilets, and a rest area with mattresses and blankets. The setup reflects the race's nature: after over five hundred kilometers, finishing may necessitate food, a shower, paperwork, transport, and a place to rest.
