Climbing during Covid

After thousands of check-ins in our gyms, we’re proud to say that we’ve got a stellar Covid track record. We’re grateful to all of the members of this community who’ve been so focused in following our Covid best practices so that we can keep the gym open for all. For those just returning to the gyms, the walls, the movement, and the fun will be very familiar to you, but a few things will look a bit different.
