Henry Horton Trail Half
A fast, relatively flat trail half marathon through Henry Horton State Park. Trail miles that flow fast in places and get properly technical in others, with classic Tennessee rocks, roots, and rolling terrain throughout.

The hook
Three things to know.
A trail half that runs fast
Relatively flat for a trail course, built for runners who want trail miles without the climbing that turns most trail halves into all-day projects. PR-friendly if that’s what you’re after.
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. It’s built for runners who love being on trail but don’t want their half marathon turning into an ultra disguised by endless climbing.
The course flows through a mix of single-track and double-track with long runnable sections balanced by classic Tennessee trail features: roots, rocks, quick footing changes, and enough technical terrain to keep you engaged. Fast in places, technical in others, it’s the kind of trail course that rewards rhythm and attention equally.
Expect a well-marked route, steady rolling terrain, and a finish that brings you back to 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.
