2023 Los Angeles Marathon and Charity Half Marathon

Thank you for your interest in running the 2023 Los Angeles Marathon / Charity Half Marathon on behalf of the National Brain Tumor Society! For both distances, we are accepting applications for runners who will obtain a bib through NBTS. If you have your own bib for the marathon from another source and would like to run for NBTS, 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 $650 fundraising commitment for runners obtaining a bib through NBTS, and the ability to safely train for the marathon or half marathon.

As a runner, you will receive:

  • Official race entry to the 2023 LA Marathon or Charity Half 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
