RUN-A-MUCK | October 3, 2026

Get Ready to Run. Muck (walk). Celebrate.

Experience one of Chester County's favorite fall traditions! Whether you're racing for a personal best or taking on the famous Mucker Course at your own pace, Run-A-Muck is an afternoon of outdoor adventure, community, and conservation.

Challenge yourself on our scenic cross-country course featuring fields, woods, streams, hills, and plenty to see along the way. Then stick around to celebrate with great food, local beer and wine, live music, a roaring bonfire, and activities for the whole family.

Every registration helps protect the natural beauty, wildlife habitat, and open spaces of the Willistown countryside.
