Your Rights When Cancelling a Gym in Denver

Residents of Denver cancelling a gym membership are protected by C.R.S. § 6-1-105. This Colorado state law gives you a 3-business-day cooling-off period after signing any gym contract — meaning you can cancel without penalty and receive a full refund within that window.

More importantly, the law allows you to cancel via written notice — no in-person visit required. A certified mail letter to your gym's home location creates a legally admissible record the gym cannot dispute.
