2025 Big Sur Charity Runner Application

DATE: SUNDAY, APRIL 27, 2025

Thank you for your interest in running the 2025 Big Sur International Marathon, 11-Miler, or 12K, 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 secured a bib through another source, such as a bib deferment or the race drawing. 

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 fundraising commitment for runners obtaining a bib through NBTS, and the ability to safely train for the race.

Fundraising Commitments:

  • Marathon runners: $2,000 
  • 11-Miler runners: $1,500 
  • 12K runners: $1,000 

As a runner, you will receive:

  • Official race entry to the 2025 Big Sur International Marathon, 11-Miler, or 12K as part of the National Brain Tumor Society’s Gray Nation Endurance® Team (for runners obtaining a bib through NBTS)
  • A personal fundraising page and fundraising tools
  • Communication from NBTS staff throughout your race experience 
  • Gray Nation Endurance team swag

Application and Acceptance Process:
When you’ve completed your application, please email Endurance@braintumor.org to confirm receipt of your application. Once received, an NBTS staff member will reach out to set up a quick call. If accepted, NBTS will notify you by email.
