I am in my 30's and am a runner and a competitor. Much of my spare time is devoted to training and racing. I am not, by racer standards, fast but I work hard to earn PRs and to place higher in each races I race.I
I place close attention to my running progress and always strive to improve.

I didn't have a good answer.
