Join us for the California International Marathon in 2025

We have had over 100 runners cross the 26.2-mile finish line for the NEC Society—and we’re just getting started! We’d love for YOU to sign up to join us in 2025.

Join the NEC Society’s Running Team at CIM 2025

The NEC Society is proudly a part of the California International Marathon (CIM) Charity Program. 

The NEC Society had 26 runners cross the finish line at CIM in 2024 in honor of babies affected by NEC. Together, we raised over $20,000 to propel the NEC Society’s work.

We want YOU to be part of the movement in 2025. Join us in running 26.2 for a world without NEC.
