Henry Horton Half Marathon
A fast, relatively flat 13.1-mile trail half marathon through Henry Horton State Park. A trail half built for actual PRs, not the kind that wreck you.

The hook
Three things to know.
A trail half you can PR
Fast and relatively flat for a trail half. The course is built for runners who want trail miles without the brutal climbs that wreck most trail half results.
Fall in Middle TN is the move
October 10 puts you right in the window when mornings feel like jacket weather and afternoons feel like a vacation. Color on the trees, dry trail under foot.
A park worth showing up to
Henry Horton is one of Tennessee’s most underrated state parks. We’re building this race to be the kind you’d road-trip for: finish line, park hang, and all.
The course (in progress)
Fast trail, fair miles.
Henry Horton is a 13.1-mile trail half marathon on the park’s soft-surface trails: rolling, runnable, and relatively flat for a trail course. Built for runners who love being on trail but don’t want their half marathon turned into an ultra by 5,000 ft of climbing.
Expect a smooth, well-marked single-track and double-track route through the park, just enough roll to keep things interesting, and a finish that lands you back at the park’s main area.
We’re finalizing the exact route in coordination with Tennessee State Parks. The map below will go live with the official course once it’s permitted.
