The B.A.A. defines net downhill as the difference in elevation between the start and finish. Starting with 2027registration, verified qualifying times from courses with at least 1,500 feet of net downhill receive an index after submission.
| Net downhill | Adjustment | Boston qualifying status |
|---|---|---|
| Less than 1,500 ft | No index | Can be submitted if the race otherwise meets B.A.A. criteria |
| 1,500 to 2,999 ft | +5:00 | Five minutes are added after the time is submitted |
| 3,000 to 5,999 ft | +10:00 | Ten minutes are added after the time is submitted |
| 6,000 ft or more | Not accepted | The course is not allowed for Boston qualifying |
The downhill index is separate from the age-group standard. Runners should confirm current course certification, course elevation, and race-specific eligibility before choosing a qualifying race.
