  3. Net-Downhill Marathons for Boston Qualifying
Happy runners on the Ogden Marathon course
(📸 America First Ogden Marathon)

The Boston Athletic Association (B.A.A.) set the running world abuzz last month when it announced its registration updates for the 2027 Boston Marathon. Most notable was a new time adjustment—termed “Downhill Results Indexing”—for Boston Marathon qualifying races with a net-downhill of 1,500 feet or greater:

  • Verified qualifying times from any course with a net-downhill of between 1,500 and 2,999 feet will incur a five-minute (+5:00 minutes) time adjustment, or “index,” to the official results for Boston Marathon qualifying purposes.
  • Verified qualifying times from any course with a net-downhill of between 3,000 and 5,999 feet will incur a ten-minute (+10:00 minutes) index to the official results for Boston Marathon qualifying purposes.
  • Any course with a net-downhill of 6,000 feet or greater will not be allowed for Boston Marathon qualifying purposes.

The B.A.A. defines “net-downhill” as the difference in elevation between the start and finish points of an event.

In other words, with a new penalty box for net-downhill courses of 1,500+ feet, qualifying for Boston just got tougher.

With this in mind, we present our comprehensive lineup of net-downhill marathons (500 ft or greater) in the U.S. and Canada, organized by BQ index: no index, five minutes, and ten minutes. Each table is sortable by race name, date, location, and of course, net elevation loss to help you find your personal BQ sweet spot!
