 Runner Perks:

  • Chip timed event
  • Entry into monthly post-race raffle drawing
  • Post race chili and other snacks 
  • Long-sleeved high performance t-shirt


The OC Chili Winter Trail Run Series benefits Trails4All, a local non-profit organization that works fervently throughout the year to provide trail access and trail clean up projects in Southern California.   They were recently awarded the OC Community Foundation grant in which they actively work with high school aged kids to encourage conservation, leadership and more. Through events such as this, grants, and community support, Trails4Alll is able to continue their efforts.   We have been able to raise over $10,000 to benefit Trails4All’s efforts
