Qualify a year ahead · April 19, 2027 (Patriots' Day)
The race you qualify for a year in advance.
Boston 2027 runs on Patriots' Day as it has since 1897, and the travel plan starts eight months early: registration is September 14 to 18, 2026, acceptance floats on how far you beat your qualifying standard, and nobody books Back Bay until the B.A.A. says yes in October. New this cycle: downhill-course qualifying times get adjusted, and a thousand extra spots go to a random draw.
