I rode my push bike from Portland to Cheyenne, WY. I figure I burnt 10,000 calories a day.The environmental cost of logistics of growing and shipping that many human consumable calories probably drastically out weighs that of burning gas in a car to travel that distance. Maybe someone can do the math.

It depends on what those calories are. If you're eating inexpensive veggies/fruits/starches/grains, you're probably around 200-300mpg equivalent on a bike. If you're eating steaks, then you're probably pretty close to a car.

You're doing a lot worse than that if you're hauling mail around.

The numbers also get a lot worse once you consider the energy cost of shipping your food to you (as both your article and the person you were responding to noted).
