so ive been running now 5 times a week now for about 2 months and have done some reading on running. my question is about lactic acid and the burn it cause, its suposed to be a good burn, so can someone describe it to me so i know when im feeling it. sometimes i have a pain horizontal to my belly button on my left side, vertically under my left nipple, but i think thats my stomach punishing me for eating too closely to a run. so back to lactic or lactate or whatever it is, please explain.
thankyou
