From 1981 to a Revival in 2004
1981The Oslo Maraton was first held in 1981 and became popular enough that the organisers call 14,200 participants in 1993 the 'magic number'. Interest fell around the turn of the millennium and the marathon was not held for several years. Sportsklubben Vidar revived it in 2004, and in 2013 more than 23,000 had signed up, so registrations were capped.
