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.

The flattest, fastest marathons for a Boston Qualifier

A Boston Qualifier is won on a fast course in cool air — usually flat, though a legal net-downhill course can be faster still. This list ranks every Boston-qualifying marathon by the two things you can eyeball — minimal elevation gain and cool, dry race-morning conditions. For the fuller picture — which folds in the BAA's downhill adjustment and an estimated course effect — see the BQ Course Finder linked below. These 10 give you the best shot at the standard.
