that is a question i've been pondering for some time -- what is the normal running distance for a healthy human? there doesn't seem to be any objective answer. i would imagine a typical unfit person would only be able to go 50 meters or so before having to stop and catch their breath.
during my regular 30 minute walks i'll jog as far as i can about 3 times before running out of breath. and after a couple of months im only up to around 200m, which is quite pathetic. i dont know what im supposed to do to improve this.
In my gym
classes in high school, we had to run 1.6kms, or 1 mile. In the first few classes we'd have physical conditioning to reach that level. I was morbidly obese and took longer than most of my classmates
