Which Planet Fitness in Longmont is closest to me?

Tap “Use my exact location” above. The list re-sorts by straight-line distance from where you are, on your own device, and every club has a Directions link that opens the route in Google Maps.

A club is missing or the address is wrong. Why?

Club locations come from two open datasets: AllThePlaces, which collects store locations from public websites, and OpenStreetMap, a map built by volunteers. Together they cover nearly every club, but a new opening can take a while to appear. We refresh our copy regularly, and anyone can add or correct a club on openstreetmap.org.

Is this the official Planet Fitness club finder?

No. This is an independent tool from Pawer, a free workout tracker. For membership, hours and class schedules, contact the club directly or use Planet Fitness’s own website.
