Frio Trio Zero Edition

Frio Trio Zero Edition is a multi‑sport festival held October 2 to 4, 2026 around Leakey, Concan, and Uvalde, TX. The event combines trail running, gravel bike racing, and river float trips with race hubs in downtown Leakey and Garner State Park. Courses are fully marked and supported with aid stations and finish line support. This Zero Edition will not include official timing or finisher medals, but top finishers will be recognized and commemorative shirts are available as an add on.

Registration was free for the first 200 entries; the next 200 entries are $25 per race registration. Race registration covers Garner State Park entry and other venue access fees paid by the organizer. Spectators are responsible for their own park entry and any venue parking or land use fees.
