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.

 
Why Run WTF West?

  • Half Marathon & 5 Mile options: Choose the distance that fits your winter goals
  • Run or ruck divisions: A growing ruck community side by side with runners
  • Unpredictable winter trail conditions: Snow, slush, ice, mud—sometimes all in one race
  • Noon start time: Sleep in and let the temps warm up before you hit the trails
  • River crossing option: Test your grit or bypass with a short detour
  • Swag you’ll live in: Earn the custom WTF hoodie and medal every finisher loves
  • Community atmosphere: High-energy volunteers, bonfires, and post-race stories to share
  • WTF + STFU Trail Series: Race Winter Trail Fest plus Summer Trail Fest Ultra (50K, Half Marathon, 5 Mile) in June to claim connecting medals and save 15% with the bundle
     

This is more than a winter race—it’s a celebration of grit, unpredictability, and Michigan’s late-February trails. Sign up for the Winter Trail Fest West Half Marathon or 5 Mile and find out why runners and ruckers come back year after year.

2026 Winter Trail Fest Finisher Medal

The 2026 Winter Trail Fest medal is designed to celebrate equal parts grit and fun—because winter trail racing should be tough, memorable, and a little bit ridiculous. Measuring 3.5 inches tall, the medal features raised text, cut-out snowflake tips, and a glittery blue finish that catches the light like the sun glinting off fresh ice.

On the back, a magnetic connection allows the WTF medal to pair with the upcoming Summer Trail Fest Ultra (STFU) medal. When combined, the STFU medal fills in the snowflake cutouts, creating a complete, glitter-filled design that represents racing through both winter and summer.

Finish WTF. Return for STFU. Connect the story.

5 Mile Event Details

The Winter Trail Fest 5 Miler is a great intro to winter trail running, or a great early season short course trail race. Athletes will traverse unique trails not used by many other events at Yankee Springs. The course has rolling hills, and is extremely well marked with confidence marker hanging tape every .1 miles, and turn signs at every turn. Runners will have the choice to cross the frigid water about .5 mile from the finish or run a bonus .25 miles and avoid the water! Either way this is an epic way to kick off your season of racing and keep you training through the cold winter months!

Here's the course map on Strava. You can view the course and elevation, as well as download a GPX file to use with your running watch.
