When I first came into international running, most runners did about 60-70 miles or running a week. I guess that is still the standard except for Kenya and Ethiopia. I was doing 150-250 a week and some weeks as high as 350. It was unheard of! But, because I did not have access to what was possible and standard, I had to set my own possibilities and standards. I was just lucky enough to be out of the loop and not know.
