The Fun Run races, sponsored by MountainOne, are open to everyone, veteran or first-time runners, as well as daily or occasional walkers.  Families with pets and strollers are also welcome to join the fun. Both race events begin at 9:00 a.m. on Saturday, September 13, 2025 at the Williamstown Youth Center, 66 School Street. In person registration opens at 8:00 a.m.

The cost for the 5K race is $15.00 per runner and for the 1 mile Walk/Run $5.00 per participant; children age 5 and under may participate at no charge.   Scholarships are available.

For 98 years, the Williamstown Community Chest has provided funding to local human service agencies and organizations that serve the northern Berkshire area.   The generosity of people, businesses, and organizations throughout our community makes this possible.

Online registration will open in July! We accept Venmo, PayPal, credit cards, cash, check.
