The Experience

The Chunky Monkey Epilepsy Run, now in its fifth year, is a heartfelt small-town half-marathon held in Blanchardville, Wisconsin. Founded in memory of Mathias Lee Koch, the race raises funds and collects blankets for families at American Family Children's Hospital. With runners from about four states and a loyal 16% returning each year, this event combines a challenging course with genuine community spirit.

The half-marathon is unapologetically hilly—the organizers warn, 'Be ready for HILLS—seriously!' The scenic course winds through the Wisconsin countryside, offering a beautiful but taxing journey. Aid stations with water and Gatorade are placed every 2–3 miles, and a generous 3.5-hour time limit (about 16-minute miles) welcomes runners of all levels. The typical winning time around 1:34 gives a sense of the course's toughness.

Post-race, participants receive a long-sleeve performance tee as part of their registration. The event's focus extends beyond running, with a blanket drive that aims to provide comfort to 200 families annually. The Chunky Monkey Epilepsy Run captures the best of small-race camaraderie: a tough, scenic course, a worthy cause, and a welcoming atmosphere that keeps runners coming back.
