The 2026 Boston Marathon, marking the 130th edition of the race, drew massive interest. Organizers received 33,249 applications, of which 24,362 were accepted. That means nearly 9,000 runners didn’t make the cut despite meeting the basic criteria. Among those accepted are runners from 120 countries and all 50 U.S. states. 1,373 participants are residents of Massachusetts — a strong local representation, as always.
