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.

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

As a runner, you will receive:
