BOSTON – The Boston Athletic Association (B.A.A.) announced today that 2026 Boston 5K registration will occur over four days in January, featuring a new random selection process. The 2026 Boston 5K will take place on Saturday, April 18, two days prior to the 130th Boston Marathon presented by Bank of America. Boston 5K registration is now open and will close at 5:00 p.m. EST on Thursday, January 29.
In response to unprecedented demand witnessed in 2025, where the Boston 5K reached its field size capacity in 21 minutes, a new random selection process has been implemented this year to allow for a more systematic approach to registration, intended to offer more athletes the chance to participate. Interested athletes can submit a Boston 5K registration application within Athletes’ Village now through January 29. Athletes will be informed if they’ve been accepted into the race over the coming weeks.
If athletes are looking for another opportunity to participate in the 2026 Boston 5K, the Special Olympics Massachusetts Xtra Mile team raises funds to provide opportunities for individuals with intellectual disabilities to thrive through the power of sport.
Additional information about the Boston 5K, registration process, and Special Olympics MA Xtra Mile team can be found on the B.A.A. website.
