Men who qualify for Boston at 70–74 represent the pinnacle of masters endurance running. The 4:20 standard, age-adjusted, reflects fitness that a small fraction of the running population at this age achieves. The training and discipline required are genuine.
Quick answer: The 2027 BQ standard for Men ages 70–74 is 4:20:00. This requires an RPI of 34.4 — equivalent to 27:22 5K fitness. Training paces: easy 10:41/mi, threshold 9:05/mi, interval 8:14/mi. WMA age grade: 64.8%.

A 4:20:00 marathon averages 9:55 per mile. Training for it is built on the long run, with marathon-pace miles added as the build goes on, threshold work at 9:05 per mile for the stamina behind marathon pace, and easy running at 10:41 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 4:20:00 marathon BQ (RPI 34.4): Easy 10:41/mi, Marathon 9:54/mi, Threshold 9:05/mi, Interval 8:14/mi. Marathon training pace (9:54/mi) is the target for the final miles of long runs. All other miles should be at easy pace or slower.
A 4:20:00 marathon at age 72 scores 64.8% WMA age-graded. At this age, the WMA factor is significantly above 1.0, meaning the standard accounts for substantial age-related performance decline from the open class. Achieving this time represents competitive running by any measure.
A 4:20:00 marathon (RPI 34.4) is equivalent to 27:22 5K fitness. This aerobic equivalency illustrates the full fitness profile of a BQ-level marathoner in the 70–74 group — competitive across all distances on an age-adjusted basis.
