Cossatot River Trail Run

Cossatot River Trail Run takes place in Wickes, Arkansas, on September 26, 2026. Organized by Texas Outlaw Running, the event offers two trail distances: a half marathon (13.1 miles) starting at 7:50 a.m. and a 10K starting at 9:00 a.m. Both are run on trails along the Cossatot River in southwestern Arkansas, giving you a compact day with a choice between a short and a medium effort.

Runners new to trails will find the 10K a manageable introduction, while the half marathon is a good goal for those who already run that distance on roads and want to try it on dirt. Neither requires an ultra-style build: 8 to 12 weeks of regular running with one weekly long run on trails, a few hill sessions, and some practice on uneven footing is plenty. Expect the trail half to take longer than a road half, and plan your pacing and hydration accordingly rather than chasing a road personal record.
