2026 Wild Thing 5K/10K Race/Walk

Join one of the wildest and most scenic trail races in the Berkshires at Mass Audubon’s Pleasant Valley Wildlife Sanctuary in Lenox, MA.

Lace up your running shoes and hit the trails for a race that’s as beautiful as it is fun. Run wild through the peaceful forest single-track and historic carriage roads of Kennedy Park, delivering just the right mix of challenge and flow.

Awards in all age groups and categories—show off your wild side in a nature inspired costume for a chance to win Best Dressed! Stick around after the race for refreshments and prizes.

Register before June 1 to receive early bird pricing. The first 200 runners will receive a free reusable tote bag.

Every step makes a difference. All proceeds support Mass Audubon’s environmental education and conservation efforts in Berkshire County.
