129th Boston Marathon qualifier: 36,393 entries, 6 minutes 51 seconds under cutoff
36,393 qualified runners chased the 129th Boston, the largest applicant pool in race history, and the cutoff hit a record 6 minutes 51 seconds under standard.
What made 2025 notable
The 129th Boston Marathon was the breaking point for the old qualifying system. A record 36,393 athletes registered with a valid Boston Qualifying time during the September window, well above the previous high of 33,058 set just a year earlier. The BAA accepted 24,069: 13,740 men, 10,260 women, and 69 non-binary athletes. To make the field, runners had to clear their age-group standard by 6 minutes 51 seconds, the strictest cutoff in BAA history. 12,324 qualified applicants were turned away. The cumulative pressure of three straight years of brutal cutoffs (4:52 in 2023, 5:29 in 2024, 6:51 in 2025) triggered the BAA's five-minute tightening of every standard starting with the 2026 race. About 11,326 accepted runners would be making their Boston debut.
