Boston Marathon 2025 Cutoff Prediction. After a record number of qualified applicants applied to run the boston marathon in 2024, there has been plenty of talk about what will happen in 2025. I set about collecting an enormous dataset to help answer these questions and predict the cutoff time for the 2025 boston marathon.

The cutoff times won’t be known until after the application period closes in september and the acceptance/rejection emails go out. For the 2025 boston marathon, the qualifying period is september 1, 2023, to september 13, 2024.
