Winter Trail Fest 13.1 and 5 Mile Eastside

Some call it the Winter Trail Fest. Others just think, “What the F…?!”

Join us 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 enoughbefore 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. Our ruck division is growing fast—ruckers, we see you.

Then, come back in June for the Summer Trail Fest Ultra (50K), Half Marathon, or 5 Mile to complete the series and claim your connecting STFU medal.
