About how many calories do I burn walking a mile?
I know it varies depending on speed and terrain, but is there a formula where I can find out how many calories I burn walking per mile?
I found something on runners world that said I should multiply my weight by .3, and that would mean that I burn 42 calories per mile...and this seems low to me. I've also seen some people say approximately 100 calories per mile, but this seems too high for me.
