do i burn more calories running 2 miles straight, really fast then i do jogging or walking 2 miles straight
and if so does that mean that i could actually burn more calories running 2 miles than i could jogging or walking 3 or more??
Rule of thumb is that you burn about the same calories per mile, but just faster (so, calories per mile is the same, but calories per hour is different)…I guess you could compare it to your car (pretty much the same mile per gallon no matter what speed, except less efficient in the city with all the stopping and starting)…so do what you like and have time for. Whaterver you do, if you occasionally crank it up a notch for intervals, your strength and endurance will improve greatly.
