Frontline OCR
About this race
Frontline OCR is more than a race. It's a tribute. The Frontline OCR Foundation is a 501(c)(3) non-profit organization. This event was created to honor the grit and sacrifice of military personnel, veterans, and first responders by putting participants through an obstacle course that mirrors the physical and mental battles faced in the line of duty.
Every obstacle is purpose-built to challenge your limits and reflects the toughness required on the real frontline. There are no shortcuts. No scheduled breaks. Just you, the course, and the chance to prove what you're made of.
This is not your average race. It's a test of courage, resilience, and readiness.
The Frontline OCR brings an exciting 10K, 1.6K to Byron, Illinois on May 24, 2025. Don't miss this beautiful event!
