Winter Trail Fest East Half Marathon & 5 Mile Brighton, MI   Feb 13, 2027

Join Trivium for WTF Eastside! Some call it the Winter Trail Fest. Others just think, “What the F…?!”

Join at Island Lake in Brighton, Michigan for a Half Marathon or 5 Mile run or ruck designed to embrace the messiest, most unpredictable conditions February has to offer. Snow? Ice? Slush? Perfect. You’ll earn every inch of your WTF hoodie, medal, and bragging rights. Worried about the cold? Don’t be. The late morning start gives you time to sleep in and lets the temps rise just enough before you hit the trails.

This race is for those who crave a challenge. The gnarlier the conditions, the cooler the participants. WTF is all about embracing uncertainty, chasing adventure, and leaning into whatever the trail throws your way. Then, hit the trails again in June for the Summer Trail Fest Ultra 50 Mile, 50K, Half Marathon, or 5 Mile to complete the series and claim your connecting STFU medal.
