It seems like no matter how hard or how long I run, I never get out of breath. I'm never struggling to breathe in races or workouts, no matter how hard. Even in terrible races when I've completely blown up, I never feel out of breath. Instead it seems like my legs are the limiting factor. Am I not pushing myself hard enough? Am I just weird? What's the deal?
I did do semi-competitive swimming for about 8 years in elementary/middle school, if that counts for anything
