Winter Trail Fest Westside Half Marathon & 5 Mile

Run Winter Trail Fest in 2026

February 21, 2026 – Yankee Springs Rec Area, MI

Some call it the Winter Trail Fest. Others just think, What The F…?! Join Trivium Racing for a winter trail Half Marathon or 5 Mile run or ruck at Yankee Springs. Expect snow, mud, ice, and the infamous river crossing—unless you take the slightly longer alternate route (+0.25 mi) to stay dry. We’re hoping for true WTF conditions, and the afternoon start gives both you and the temps a chance to warm up before you hit the trails. Earn your WTF hoodie, epic medal, and bragging rights the hard way. WTF West draws a wild mix of first-time trail runners, die-hard winter warriors, and ruckers ready to grind. Come for the challenge, stay for the bonfires, and leave with a story you’ll tell until the snow melts. Then join us in June for Summer Trail Fest Ultra (STFU) 50K, Half, or 5 Mile to complete the magnetic medal series set.
