2023 Boston Marathon

Thank you for your interest in running the 2023 Boston Marathon on behalf of the National Brain Tumor Society!  We are accepting applications for both runners who will obtain a bib through NBTS and runners who have qualified for the Boston Marathon or have a bib through another source.  If you have your own bib and would like to run with the NBTS team, please email

NBTS is evaluating applications based on applicants who have a connection and/or passion to further the NBTS mission, the ability to meet and exceed the $10,000 fundraising commitment for runners obtaining a bib through NBTS, and the ability to safely train for the marathon.

As a runner, you will receive:

  • Official race entry to the 2023 Boston Marathon as part of the National Brain Tumor Society’s Gray Nation Endurance Team
  • A personal fundraising page and fundraising tools
  • Communication from NBTS staff throughout your race experience 
  • Gray Nation Endurance team swag
