Starting a parkour gym

Is it primarily a place for teaching parkour? Do you want more of an “open gym” format? Who do you want to reach?

Who do you want to be like? Visit (virtually or in meatspace) other gyms and figure out exactly what you want to do. Are you interested in teaching on squishy/springy equipment like gymnastics gyms? Are you interested in Ninja Warrior style challenges? Whose gyms do you like? Why?

Once you have a clear picture of what you want your space to look like, you'll be better able to figure out how much space and materials you'll need. Then you can check your local real estate and hardware/lumber markets, etc.

You'll need qualified coaches: good people who know what they're doing and know how to serve your community.

Look in detail at the laws in your area to see what kind of permits, licenses, and insurance you'll need.

Start looking for insurance yesterday. Parkour is still new. Many insurance companies don't know enough about it to be willing to underwrite it reasonably. It will take you some time to find a company willing to underwrite you. You'll need a general liability policy to start. We recommend finding a good local broker to talk to.

Write a business plan. You'll probably discover most of answers to the above questions while writing it. Remember, the plan itself is of marginal use, but the act of planning is invaluable.
