I mostly compete with myself. I am trying to do better now than I did earlier.
It helps that progress in my main forms of exercise (indoor climbing, weight lifting) is easy to measure, and relatively straight forward to drive at my level.
I also dable in dancing, where I am still so awful, that progress is easy to gauge. And mixed martial arts, where the whole point of the sport is some form of competition, even though sparring doesn't see you go all out.
