MTNTOUGH - Backcountry Calorie Calculator - Access

Here’s the link to download your Backcountry Calorie Calculator:

The Backcountry Calorie Calculator is an excel file, and unfortunately, iPhones will open this as a read-only preview version by default. We recommend you use it on a computer, but to be able to use it on your phone, all you need to do is open it with either one of those free apps: The Apple Numbers App or The Microsoft Excel App.


Remember: When your body burns more calories than it consumes during heavy exertion, especially during a multi-day event like hunting, it creates the conditions for a severe energy crash.

On-mountain performance (strength, stamina, and mental clarity) will gradually decrease as a hunter's calorie deficit increases day after day. Basically, try to manage the calorie gap, between your daily burn and daily consumption, especially over multi-day expeditions.

This is why we developed this calculator for you.

Test it and use it plan your hunts.

Let us know how it’s working for you, and feel free to send us your calorie data if you’re using a device to track it yourself.

As we learn more about new research and gather more data, we’ll be updating this document to make sure it’s as accurate as it can be.

You’ll receive revision updates whenever we release them.

Right now, we utilize what's known as the "ACSM" or "Pandolf" equations, which were initially developed for the military and have been used since the 1970s to estimate how much energy it takes to hike with a heavy pack on.
