The Headwaters of the Frio Trail Marathon, Half, 12K, 5K is a challenging run/walk event across the rugged and isolated terrain of one of the most stunningly beautiful ranches in the Texas Hill Country. This event, held during Child Abuse Prevention month, highlights the vital mission of Hill Country Youth Ranch and Big Springs Ranch for Children which work to bring healing and restoration to children who have been victims of horrific abuse, abandonment and neglect.

This is truly a special event, and we’re looking for a special kind of participant! If you’re the kind of person who finds joy and fulfillment in physical challenges like marathons, half marathons, 12K’s or 5K’s whether running or walking, AND have a desire to help kids by supporting worthy nonprofits like Hill Country Youth Ranch / Big Springs Ranch for Children, you’re just the kind of person we’re looking for!

This is a fundraising event with a $35 registration fee (waived for returning participants) plus a $250 fundraising commitment or donation, in order to participate, regardless of which distance is chosen.

Limited to 250 total participants across the 4 distance categories; plan now to join us for our 3rd annual event!
