Starting running

If you start to feel pain anywhere, take a fucking break. I ran a 10k through some mild ITBS like a dumbass and 4 months later I can't run further than a mile without it feeling like someone is hammering a nail into the side of my knee.

Other than that, just work on form. Make sure you don't have any anterior pelvic tilt going on, run at a pace you can comfortably hold a conversation at if your goal is distance, and increase your mileage by about 10% every week, assuming you run 3 days out of 7.

Running long distances is about 90% in the mind. If you can overcome that aspect of it,it gets so much easier

Your biggest enemy is your attitude. If you cant stop yourself thinking shit like you can't go any further or you gotta stop then you'll never get gud.
