Winter Trail Fest West – Half Marathon & 5 Mile Trail Race in Middleville, Michigan
Some call it the Winter Trail Fest. Others just think, “What the F…?!”
Join us on Saturday, February 21, 2026, at Yankee Springs Recreation Area in Middleville, MI for Winter Trail Fest West Half Marathon and 5 Mile trail race. This winter race is known for its unpredictable conditions—snow, slush, ice, or mud—and the famous river crossing that takes “winter trail challenge” to another level. If icy water isn’t your thing, you can skip it with a short .25-mile detour, but either way, you’ll earn every step of your WTF hoodie, medal, and bragging rights.
WTF West begins with a Noon start, giving you a chance to relax in the morning before testing your grit on the trails. The Half Marathon course features rolling hills and rugged singletrack, while the 5 Mile distance offers a fast, fun taste of winter racing. Both distances welcome runners and ruckers, making WTF West one of Michigan’s few winter trail races to feature a dedicated ruck division.
This race is perfect motivation to keep training through the winter months. Signing up for WTF West means having a goal to keep you moving when the weather makes most people stay inside. The gnarlier the conditions, the cooler the participants—and at WTF West, you’ll never forget the experience.
