Welcome to the double hippy club! I do envy your level of fitness, which I am sure will help you recover quickly. Not as quickly as you would like, of course, that goes with the territory! But just think what a star you will become with two good hips.
I was anxious before my second op, remembering all the worst bits of the first recovery. But I did find, after a rough few days to start with, that being better prepared made it easier. Also, although one of the things that I was dreading was having to sleep on my back, that was much easier this time. Perhaps because I knew that was how it would be for a while, and so accepted it. And side sleeping came more quickly this time. I hope it will be the same for you.
