The update does not regulate marathon training; it changes qualification and registration for the April 19, 2027 Boston Marathon. The main measures are adopted rules, not proposals, and the active lawsuit concerns alleged spectator discrimination rather than 2027 entry standards. A Boston qualifier is a runner who completes an eligible marathon within the time standard for their age and gender category. Qualifying permits an application, but it does not guarantee a race place.

What changed for 2027 entry?
The Boston Athletic Association, or B.A.A., added a random selection for roughly 1,000 qualified applicants. It applies only to runners who meet their category standard but miss the faster cut-off used to fill available places. The normal selection process still comes first. The B.A.A. verifies applications and ranks runners by how far under their qualifying standard they finished.
Applicants who beat the eventual cut-off receive priority; slower qualifiers may enter the random selection. This is an implemented policy for 2027, not a rule awaiting approval. The B.A.A.'s July 22 announcement describes both the ranking process and the additional random-selection route. The practical effect is limited but meaningful. A runner just outside the cut-off now has another chance, while a faster qualifying time remains the more reliable path to entry.
Who can apply, and when?
Runners with valid qualifying times for their age and gender categories may apply from September 14 through September 18, 2026. The B.A.A. says it will notify all applicants by early October. Before applying, check four points: Do not treat the qualifying standard as a target that ensures admission.
A training plan aimed at exactly that time may produce an eligible application without securing direct entry. Building an appropriate margin below the standard can improve ranking, although no specific margin guarantees acceptance. Current category standards and qualification details appear on the B.A.A. 2027 qualification page.
- Your result meets the standard for the applicable age and gender category.
- The race meets the B.A.A.'s course and event requirements.
- Any downhill adjustment still leaves your result within the standard.
- Your submitted race details can be independently verified.
How do downhill and race-format rules work?
For 2027, the B.A.A. adjusts qualifying results from courses with substantial net elevation loss. "Net downhill" means the elevation difference between the start and finish, not the total descent accumulated across every hill. A course dropping 1,500 to 2,999 feet adds five minutes to the submitted result. A drop of 3,000 to 5,999 feet adds 10 minutes. Courses losing 6,000 feet or more are ineligible, according to the B.A.A.'s downhill-indexing policy.
For example, a 3:20 finish on a course with a 2,000-foot net drop is evaluated as 3:25. That adjusted time—not the clock result—determines whether the runner meets the relevant standard. The B.A.A. says it based the policy on race results from 2022 onward and scientific studies. However, its announcement does not link the underlying dataset or cited studies. Readers can understand the rule's operation, but they cannot independently assess the full evidence from that notice alone.
Which marathon results are eligible?
An eligible result must come from a certified, outdoor full marathon. Virtual races, treadmill or indoor marathons, time trials, and handicapped marathons do not qualify. The B.A.A.
may review and verify any submitted event or result. A runner choosing a qualifying race should therefore confirm certification and format before registering, especially when a course uses an unusual layout or timing arrangement. These restrictions concern the qualifying performance, not the runner's preparation. The policy does not dictate weekly mileage, workouts, coaching, footwear, nutrition, or other training choices.
Does the pending lawsuit challenge these entry rules?
No identified ruling connects the active case to the 2027 qualification changes. In *TrailblazHers v. B.A.A.*, spectators allege racial discrimination connected with the 2023 race. In December 2025, the federal court allowed an amendment to the case.
That procedural decision was not a ruling on the truth of the allegations, nor was it a merits decision about the 2027 entry system. Runners should separate these issues when evaluating headlines. The qualification rules determine which race results may support an application and how applicants receive places; the lawsuit concerns alleged treatment of spectators at an earlier event. For an application decision, use the B.A.A.'s published 2027 standards and calculate any downhill adjustment before the September 14–18, 2026 registration window.
