Six loops of Michigan singletrack wrapped in live music and Woodstock festival vibes
The Hallucination 100 Mile is the flagship event of the Run Woodstock festival — a groovy 100-mile ultramarathon on a repeating 16.6-mile single-track loop through the forests of the Pinckney Recreation Area in Michigan. Runners complete six clockwise laps of the course starting Friday at 2PM, running through the night and into Saturday. With full hot food at the Hog Farm base camp on every loop and aid stations every 3–6 miles, the race blends serious ultra challenge with a festive, fully-supported atmosphere. The course winds through wooded Michigan singletrack with roots, rocks, and rolling hills, crossing gravel roads at several points. A Western States 100 qualifier, the Hallucination 100 draws a mix of seasoned ultrarunners chasing its legendary belt buckle and first-timers drawn in by the unique music festival vibe.
