Top 50 Percent Age Group Rule

To earn Priority Registration in 2022, adult racers needed to finish the 2021 race in the top 50 percent of their age group. This rule, approved by the Mount Marathon Race Committee in 2020, replaces the First 225 Finishers Rule for gaining Priority Registration.

  • This rule is intended to substantially increase the number of lottery spots and the lottery selection odds. It is also designed to improve the chances of regaining a spot for those who lose priority status. 
  • Why was this rule necessary? In 2022, there would have been more racers with priority status than spots available, threatening the ability to even hold a lottery had the First 225 Finishers Rule not been changed.
  • To ensure that inspirational older participants are not displaced, the existing Top 10 Age Group Finishers Rule for Priority Registration will remain. 
  • Those with 10-Year Status retain Priority Registration.
