2025 Wild Thing 5k/10k Race & Walk

9:00 am Start Time 

Ready, set, GO! Lace up your running shoes and hit the trails for one of the most scenic races in the Berkshires! Wild Thing takes you through the stunning forests and rolling carriage roads of Kennedy Park, starting and finishing at Mass Audubon’s Pleasant Valley Wildlife Sanctuary. Choose the 5K route through hardwood forest or challenge yourself with the 10K course.

After crossing the finish line, celebrate at the big red barn with food, music, and a chance to win prizes from local businesses. Top finishers will be awarded, plus race swag for all participants. Feeling creative? Show off your wild side with a nature-inspired costume for a shot at "Best Dressed!"

Every step supports conservation! Proceeds from Wild Thing help fund Mass Audubon’s environmental education and conservation efforts in Berkshire County.
