# How to accurately tell how many calories I burn bike riding?

Okay so.. I ride my mountain bike everyday. I am very into it and I have ridden everyday for the past 4 years. I know how many calories I burn per mile and per hour, but is there an actual device/calorie counter that I can buy specifically for bike riding?

To the best of my knowledge - there is NO 100% accurate way to tell. Some bike computers have a built in calorie counter - such as these two...

But it's all a "best guess" kind of deal.

There is not such a thing as a calorie meter. Even the best and the closest you can get will be just a mathematical computation of your weight, speed, distance, elevation, and many other factors. Still, each person has a variable as calorie burning efficiency. Two persons of the same weight, riding together the same distance and at about the same speed will still burn different number of calories just like you will have different heart rates.

35 calories per mile is about as much accuracy as you need anyway,

If you have a smartphone, download mapmyride. It will map where you have ridden, your average speed, max. speed, calories burned, distance covered, elevation climbed etc etc. Its hard to measure calories accurately though, since your weight affects how many calories you burn aswell as the intensity at which you ride. These calorie counters dont take into account factors such as temperature or wind which can have a big impact.

Closest you're going to get is with a powertap hub.

That will give you power generated (at the rear wheel) with reasonable accuracy. There can be a fair amount of variability from one person to the next in mechanical efficiency (getting power to the rear wheel). This can be affected by bike position (seat height, seat tube angle, top tube and stem length, bar height), efficiency of the drive train (gear selection, type of shoes and pedals you use), and your personal geometry (bone lengths, muscle attachment points).

Your'e still left with the error involved in calculating calories in the mouth vs. your digestive efficiency, which can vary significantly from one day to the next and with the mix of food you eat that day.

Numbers I've seen for digestive efficiency run in the 20-30% range. I've done some back of a napkin calculations that don't disagree with that.

To actually measure calorie consumption, you'd need to spend a lot of time hooked up to tubes, hoses, and electrodes in a roomful of very expensive analytic equipment. Been there done that as a guinea pig in Gatorade's basement lab.

Bottom line: the oft-quoted range of 30-40 calories per mile is as good a number as any for your purposes.

Figure about 35 calories per mile.
