(i'm not sure if i'm posting this in the right place, so just let me know)
last week and this week I ran/attempted to run (didn't cut it last week) a 5K. I've never done this before in my life. I've never been a fast runner ( over an 11 min/mi) so I was really surprised how willingly my body did it this time (and even with how far I got last time). But then, when I'm done and I've cooled down, I'll just start bawling for no reason. I'm not in pain and I'm not happy or sad, it's more of a physical thing. I just sit there and cry my heart out (sobs and everything). Why is this? Does this happen to anyone else?
