Boston Marathon 2027 – New Qualification Rules for Net-Downhill Marathons
For years, the Boston Marathon has set the standard in the world of long-distance running. In 2027, a significant change awaits, one that will directly impact the qualification process – especially for those achieving their qualifying times on courses with substantial net-downhill elevation. This is a response to analyses that have shown marathons with a net drop of more than 1,500 feet (457.2 meters) provide runners with a significant time advantage.
What Are the New Rules?
Starting with qualification for the 2027 Boston Marathon, results achieved on courses with a net elevation drop greater than 1,500 feet will be subject to special time adjustments (known as an “index”). This means your official time will be “lengthened” accordingly during the verification process by the B.A.A.
Indexing Details:
• Courses with a net drop of 1,500–2,999 feet (457.2–914.1 meters): 5 minutes will be added to your official qualifying time.
• Courses with a net drop of 3,000–5,999 feet (914.2–1,828.5 meters): 10 minutes will be added to your qualifying time.
• Courses with a net drop greater than 6,000 feet (1,828.6 meters): results from such courses will not be accepted for Boston Marathon qualification.
These rules will be in effect for at least two years, and the B.A.A. reserves the right to make further changes as needed.
Examples of How the New Rules Apply:
• Example 1: An 18-year-old man with a standard of 2:55:00 runs 2:45:30 on a course with a 2,000-foot net drop. After adding 5 minutes, his qualifying time is 2:50:30—he qualifies.
• Example 2: A 40-year-old woman with a standard of 3:35:00 runs 3:20:30 on a course with a 5,000-foot net drop. After adding 10 minutes, her qualifying time is 3:30:30—she qualifies.
• Example 3: A 35-year-old man with a standard of 3:00:00 runs 2:58:00 on a course with a 2,500-foot net drop. After adding 5 minutes, his qualifying time is 3:03:00—he does not qualify.
Which Marathons Are Accepted for Qualification?
• The marathon must be a full distance (42.195 km / 26.2 miles) with at least three official participants.
• The course must be certified by USATF, World Athletics, AIMS, or the relevant national governing body.
• Results from virtual marathons, treadmill runs, time trials, or indoor marathons are not accepted.
• Organizers must submit proof of certification and course elevation to the B.A.A. no later than July 1 each year.
What Does This Mean for Runners?
The new rules are designed to level the playing field and ensure fair competition for all marathoners. When planning your qualifying race, be sure to check the course profile and elevation to avoid disappointment during Boston registration.
