# How Many More Calories Do You Burn Walking Uphill?

Updated June 28, 2014

It certainly feels like you are burning more calories when you walk uphill or add incline to your treadmill workout. But how many more calories are you burning by walking uphill?

The answer comes from two sources. First, our walking calorie calculator, I use MET measurements from research conducted by Barbara A. Ainsworth. In her research, they measured the actual calories expended by people walking uphill at a brisk 3.5 miles per hour with those walking on flat, firm ground at the same speed. The difference was an increase of calories burned by 60% or by an additional 48 calories per mile for a 150 pound person. On flat ground, that person would burn 80 calories per mile.

Downhill
But unless you are on a treadmill, what goes up must come down. Do you lose all of that extra calorie burn because you were going downhill for part of your walk?

No, when going downhill you only burn 6.6% fewer calories per mile than walking on the flats. That means burning 5 fewer calories per mile for our 150 pound person. Overall, by adding a one mile uphill followed by a one mile downhill, that person burned 43 more calories than they would have walking a flat two miles.

Incline
But incline also makes a big difference. Not all hills are alike, they have different inclines (percentage grades). On a treadmill, you can accurately set your incline by 1%, 2%, etc. When walking outdoors, you need to use a tool such as MapMyWalk.com to map out your walks and see what the incline really is.

I can tell you from experience, that a 5% incline is a real huffer-puffer.

The second method uses the equations from the American College Of Sports Medicine's Resource Manual for Guidelines for Exercise Testing and Prescription (courtesy of Wold Fitness Notebook) I find that:

• for every 1% of grade, you increase your calories burned by about 12% or about 10 more calories per mile for a 150 pound person.
• By the time you are at 10% grade, you are burning over twice as many calories per mile.

This is why hiking is often listed in calorie calculators as burning many more calories per mile than walking.
