putting an outlet on a free standing patio

[Mysticjoy]

My husband and I recently built a free standing concrete patio with a gazebo and I would love to have electric out there. I figured we would run the electric from the garage which is about 25 ft away. The only problem is I have no idea how to accomplish this, any advice is appreciated ! Thanks

I have included a diagram on how to do this - 12/2 UF would be the cable of choice. A GFCI receptacle would be required because of the code requirement.
