The Mt. Marathon Race made some major changes to the 2013 adult race application process. The priority registration system used before 2013 was no longer sustainable because the number of priority applicants almost exceeded the available slots which resulted in very few runners gaining entry into the race. The new priority system opens up about 125 lottery slots for each of the men’s and women’s races. This change will also benefit former runners who lost their priority status and want to regain a slot.
