Gyms & Fitness in Marlborough, MA

Written & reviewed by Founder, SEO Local · 22 years in SEO · Updated November 2026 · LinkedIn

How the US Census, they do these business counts? Middlesex County in Massachusetts has 347 gyms listed. I looked around on OpenStreetMap and found five of them that are mapped by name. One of those listings actually includes a phone number. Another one links to their website. It's pretty neat; all the listings are free, and if you’re an owner, you can claim your page on hashtag.org. That’s easy enough!
