How far can the normal person run
Depends on who or what is chasing them.
Every person's stamina is different. Someone in good shape and exercises can run farther. But,....in general, every person can run until they fall down.
after about 1/2 a mile, I start getting tired, Im short distance, but if I was getting chased by a bear, well whole other story.
I run like 8 miles and I'm finished.
Hard to say for every person but the Indians in south America can run a amazing 36 hours while chewing on coca leafs
As far as you set your mind to.
About the average person, I can't say. But studies have shown that with training humans can run further distances than any other animal on the planet, even horses. So we are designed for running.
