Ranked by Net Downhill (start to finish elevation loss). Use this guide to find courses with downhill profiles, view Boston Qualifier (BQ%) trends, and prepare for the 2027 Boston Marathon course adjustments.
The total elevation difference between the start and finish lines. A higher number generally indicates a steeper descent, which can lead to faster times but may incur time penalties for Boston Marathon qualifying.
