toppløp

Toppløp is a Norwegian term that combines topp meaning "top" and løp meaning "run" or "race." In Norwegian sports language, toppløp is used as a generic label for uphill running events. There is no single international governing body or standardized rules for toppløp; instead, individual clubs, event organizers, and regional federations define course formats, distance, and elevation gain.

Typically, a toppløp event consists of a course that ascends a mountain, hill, or alpine slope, with a mix of forest trails and rocky sections. Distances often range from several kilometers to ten kilometers or more, and elevation gain can be substantial. The format may be a standalone race or part of a broader trail-running program. Timekeeping is usually by chip timing or checkpoint stamps, and safety provisions emphasize weather exposure and terrain difficulty.

Toppløp is related to trail running and mountain running and overlaps with hill climbs and uphill endurance events. The term has gained regional usage in Norway, particularly in communities with access to mountainous terrain and ski areas, and is sometimes used in promotion of outdoor fitness events.
