Overview

Held in Terre Haute, IN, the Hawthorn Half Day 12 Hour Run is a timed loop event scheduled for May 29, 2027. Rather than chasing a fixed finish line, runners spend 12 hours accumulating mileage on a 3.1 mile circuit within Hawthorn Park. The continuous circuit keeps aid and gear access recurring every few miles throughout the full half-day limit.

The rolling route covers 75% trail, blending off-road ground into what is otherwise structured as a sub-5km loop road race. First run in 2016, the event reached 10 editions by 2026, when 50 runners logged finishes against the clock.
