The flattest, fastest marathons for a Boston Qualifier
A Boston Qualifier is won on a flat course in cool air. We took every Boston-qualifying marathon in the catalog and ranked it by the two things that make a course fast — minimal elevation gain and cool, dry race-morning conditions over a 10-year history. These 10 give you the best shot at the standard.

Frequently asked
- What's the flattest marathon for a Boston Qualifier?
- The flattest BQ courses in our catalog have under ~15 ft of climb per mile — pancake-flat. Combined with a cool race morning, these are where most qualifying times are run.
- Do downhill marathons count for Boston?
- Net-downhill courses can be Boston-qualifying, but the BAA applies a downhill adjustment to some of them, and the descent shreds your quads. Our score docks heavily-downhill courses for that reason.
