    I’ve visited this location several times and a consistently had issues with the treadmills being out of calibration. Just this morning, the machine showed 5.75 miles while my Apple Watch measured 5.0 miles, a big gap if you’re training toward specific running goals. I mentioned it to manager, and he said maintenance has looked into it but there isn’t a fix. I understand equipment wears down, but the inaccuracy seems to be present across multiple machines, which makes it hard to rely on them for pace or distance. Just a headsup to runners: until the treadmills can be recalibrated or updated, they’re not reliable enough for accurate training.

    Nice facility, very clean too. I've been to several planet fitness locations around Denver, this one was the quietest. I liked the different areas and variety of equipment. I really liked the massage chair after.
