# Hiking Calculator

*“Energy cost of walking and running at extreme uphill and downhill slopes“*Journal of applied physiology (Sep 2020)

If you're wondering **how many calories last weekend's hike burned off**, then is hiking calculator is for you. Years and seasons pass, but hiking is still as popular as it's ever been. We tend to do a little hiking to stay fit, spend time with our loved ones, meet new folks and explore the natural beauty of our planet. If we can't find time during the week to jog, play squash or even bike to work, we even treat those little hiking retreats as a chance to lose a bit of weight. And it's definitely a good thing.

Read on to find out the science behind this hiking calculator, how to use it, and an example calculation.

## Calculating calories burned

Calculating calories burned during various kind of activities is a fairly simple matter as it revolves around the following equation:

`Calories burned = MET × Weight (kg) × Time (hrs)`

MET, short for **metabolic equivalent**, is the amount of oxygen used for particular activities, such as running, walking up the stairs or cycling. You can check here the for different activities. As an example, person weighing 70 kg (154 lbs) who jogs for an hour will burn approximately `70 × 7 × 1 = 490`

calories. Although this result is only approximate, it can serve as a good starting point for our further calculations.

Back in 2002 a group of researchers treadmill and started testing how much oxygen they use at different gradients, starting from the flat walk or run and climbing higher and higher.

in the Journal of Applied Physiology entitled, "Energy cost of walking and running at extreme uphill and downhill slopes". They put a group of volunteers on aAfter a thorough research, they were able to **determine how the slope of a hill or mountain affects the amount of oxygen used** and, as a result, energy consumed. Having calculated that, they were able to come up with the equation which roughly allows comparing calories burned on a walk and a hike. From there, it was only a short way to use the aforementioned equation and calculate the energy levels for both climbing up and down.

## How do I use this hiking calculator?

We took the inspiration for this calculator from the very similar tool published several years ago on

. And it goes like this:**Enter the length**of your trail (**one way**) as well as its**elevation gain**(the sum of every elevation hiked during the trail) into the hiking calculator. This information should be available online, as well as at the trail itself.- Add your
**body weight**. - Enter your
**backpack's weight**(skip if you're not taking one — though, how will you carry your food and water?). - Once you have those 4 numbers filled in,
**all calculations will be performed**, and you'll see your approximate results.

## Example hiking calorie calculation

Let's discuss a simple example to make things clear. Mark went on a hike last weekend which lasted for 12 miles (19.3 km) in total (so **6 miles one way**) and featured a **2500 ft (762 m) elevation gain**. Mark is pretty slim himself, weighing **150 pounds** (68 kg) and carrying **18 pounds** (8.15 kg) of backpack on his back. As you can see from the calculator, the trail averaged around 7.9% grade (remember to use the one-way distance — 6 miles).

Now that we have those numbers, we can calculate the **number of calories burned** on the way up and down. First, if Mark were to leave his backpack before the trail start, he would burn roughly **924 calories for the way up** and **533 for the way down**. In total — **1457 calories**. Add the backpack and the numbers go up — **998.5 kcal for going up** and **575.5 kcal down**. In total, Mark should expect to burn around **1574 calories** during his hike.

Now, keep note that we based those formulas on a **research done in a lab and not on a mountain slope**. This means many outside factors were not taken into consideration such as Mark's stamina and individual predispositions, weather conditions, trail structure and speed of hike. Unfortunately, we simply don't have the sufficient amount of data, so can **only offer approximate values**.

Regardless, it should work as an interesting way to check the calories needed for each trail and could help hikers better prepare for their trips. Use the tool responsibly and **don't forget to take some water and food with you**, even if you're headed just for a short walk. Best of luck!

## FAQ

### Is hiking good for losing weight?

Yes, hiking is good for losing weight. On average, steep and more demanding paths make for a fair amount of calories burned. However, running still makes you burn more calories. A very rough approximation of the calories burned is `450 kcal`

per hour of hiking. Compare it with `300 kcal`

for walking and `600 kcal`

for running.

### How many calories do I burn on a 20 km hike with an elevation gain of `1000 m`

?

If you weigh around `80 kg`

(`~180 pounds`

) and you plan a `20 km`

hike with an elevation gain of `1000 m`

, you'll burn approximately `1200 calories`

. Remember that this number is just an estimate. However, if you are planning on losing weight (or just being healthy), you should definitely pack your backpack and hit the trail!

### How many calories do you burn on the Pacific Crest Trail?

A lot! For a cross-country hike with:

- Length
`4270 km`

; and - Elevation gain
`127 km`

;

the calories burned are more than `200,000`

, corresponding to a weight loss of almost `30 kg`

. Needless to say, packing enough food (and water!) is a must.

### How much food should I pack for a day of hiking?

About `3000 kcal`

worth of food. Even though this value is an estimate, if you are hiking for `30 km`

with an elevation gain of `3000 m`

, your body would burn `3000`

calories. If you are not planning to lose weight, you should plan to bring with you an adequate amount of food.
