2026 Los Angeles Marathon and Charity Half Marathon

Thank you for your interest in running the 2026 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 endurance@braintumor.org.

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 $675 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 2026 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 
• Gray Nation Endurance team swag
