Course
A timed-loop trail ultra in the Southern Kettle Moraine Forest at Eagle, Wisconsin. All loops start and finish at McMiller Trailhead, and runners mix and match a 3.1-mile green loop (160ft), a 4.93-mile purple loop (551ft) and a 6-mile modified blue loop (600ft) for as many laps as they can manage in 6, 12 or 20 hours. A cabin at the trailhead serves hot drinks and food throughout. The field is capped at 150.

About
The trail winds through golden woods, leaves crunch beneath your feet, and the autumn sun slices through the trees like a promise. Your breath is visible in the cool air, your legs burn, your heart pounds—but you feel alive. We're an uncommon group. A little wild, a little weathered, but fiercely loyal. We show up not because it's easy, but because it's hard. Because discomfort reveals something real. And the good news? You're not alone. We've got your back—and so do the other runners chasing the sun, chasing something deeper.
