Yes but, don't you only need to run to burn off the extra calories? If you stick to your ideal calorie intake why the need to run? If it's 2500 calories I'd think you only need that 8.5 miles of running when consuming 3350 daily calories.

True, but like the original comment suggested, a calorie is not a calorie. If you eat 850 calories worth of fat and protein in the morning instead of sugary carbs I am pretty certain your intake the rest of the day will be very different.
