Spenst Skjebergrittet is a mountain bike race held in Skjeberg, Norway, each June, organized by Skjeberg Cykleklubb. It is the fourth and final marathon round in the Norgescup Marathon calendar, but also includes tour classes for those who prefer to ride the route without competing at the cup level.
The organizer lists the main course at 81 km, featuring approximately 90 percent singletrack, making it a trail-focused event rather than a gravel ride. The start, finish, and assembly area are conveniently located near the E6 highway, simplifying logistics for a forest-based mountain bike event. The Norwegian cycling site Terrengsykkel described it as "quality over quantity," calling the course a cyclist’s dream and a gem.
