Overview

Perseløpet ultra 100km, organised by Feiring IL, is a road race in Eidsvoll, Norway. The course is a 2633-meter circular road loop. With 10 meters of elevation gain over 100 kilometers, the course has 0.1 meters of climb per kilometer, making it flatter than most 100k races.

The race has a time limit of 14 hours, which results in a cutoff pace of 8.4 minutes per kilometer. This cutoff is tighter than 75% of comparable 100k races, leaving less margin for error than most events at this distance. The field size of 13 finishers in its latest edition means it has a smaller field than 24% of its peer group of 314 100k races.
