A 4:50 Boston qualifier for women 70–74 is among the most impressive achievements in recreational running. The WMA age grade for this performance reflects genuine elite masters fitness. Women in this group are outliers by almost any measure of athletic longevity.
Quick answer: The 2027 BQ standard for Women ages 70–74 is 4:50:00. This requires an RPI of 30 — equivalent to 30:41 5K fitness. Training paces: easy 11:25/mi, threshold 9:55/mi, interval 8:49/mi. WMA age grade: 67.5%.

A 4:50:00 marathon averages 11:04 per mile. Training for it is built on the long run, with marathon-pace miles added as the build goes on, threshold work at 9:55 per mile for the stamina behind marathon pace, and easy running at 11:25 per mile or slower to carry the volume. How much easy running you need between hard sessions is individual. It shows in how your next workout goes, not in your age.
Running a BQ time opens the registration window — it does not guarantee entry. BAA applies a cutoff buffer each year based on how many runners qualify relative to available field spots. For the most accurate and up-to-date cutoff information, refer to the official BAA registration page at baa.org during the registration window for your target race year. From the 2027 race, times from courses with 1,500 feet or more of net downhill carry an added index of 5 or 10 minutes, and courses with 6,000 feet or more of net downhill do not qualify.
For a 4:50:00 marathon BQ (RPI 30): Easy 11:25/mi, Marathon 11:02/mi, Threshold 9:55/mi, Interval 8:49/mi. The easy pace (11:25/mi) is the foundation of all training. Marathon training pace (11:02/mi) is reserved for the final miles of the longest runs.
A 4:50:00 marathon at age 72 scores 67.5% WMA age-graded. The substantial WMA age factor for this age group means that achieving this absolute time represents competitive performance by masters running standards. This is not a low bar — it requires the aerobic engine of a trained endurance athlete.
A 4:50:00 marathon (RPI 30) is equivalent to 2:21:19 half marathon fitness. This cross-distance check is useful for benchmarking aerobic capacity as marathon preparation progresses.
