Need to update your qualifying time for the Boston Marathon?
The deadline to submit an updated qualifying time to potentially improve your seeding in the 2017 Boston Marathon has passed. Submissions were taken until Wednesday, February 1, 2017 at 5:00 p.m. ET.
If your improved qualifying time was achieved within the qualifying window for the 2018 Boston Marathon (from Saturday, September 17, 2016 through the registration period for the 2018 race), then in addition to using that time to improve your status in the 2017 race, you may also use that time to submit a registration for the 2018 Boston Marathon. Registration dates for the 122nd Boston Marathon will be announced at a later date.
* Please allow time for your qualifying time to be verified. The timing of this process will vary from submission to submission.
