Geocaching turns a simple walk into a treasure hunt, and the calories you burn depend on much more than the kilometres you log. This geocaching calories per km calculator estimates energy expenditure from your body weight, the terrain you cover, your walking pace, and the weight you carry. Whether you are strolling between urban micro-caches or climbing a wooded ridge for a large ammo can, the estimate adjusts to your adventure.
The tool applies MET (metabolic equivalent) values from exercise science to walking, hiking, and off-trail movement. Choose one of five terrain descriptions, set a leisurely or brisk pace, and optionally add a backpack. You will instantly see calories per kilometre, a total for your planned route, and an estimated time on the trail.
It is designed for casual geocachers, weekend bushwalkers, scout groups, and anyone who wants to appreciate the gentle but surprisingly real movement hiding in a hobby.

Estimates are based on average MET values and will vary with fitness, terrain conditions, and how much time you spend standing still while searching.
How the Calories Are Estimated
This calculator estimates energy expenditure using the MET (metabolic equivalent) method, a standard tool in exercise science. One MET is roughly the energy your body uses at rest, about 1 kcal per kilogram of body weight per hour. An easy walk on a sealed path may sit near 3 METs, while scrambling uphill to a cache or bush-bashing towards a remote ammo can can push the figure above 6 METs.
The underlying calculation is kcal per km = MET × 1.05 × body weight (kg) ÷ speed (km/h). The 1.05 factor adjusts the textbook MET baseline for the realistic energy cost of moving. The calculator combines a terrain base MET, a pace multiplier, and a backpack-load multiplier to produce an effective MET and an assumed walking speed.
Worked Example
Example: A 70 kg geocacher takes a 5 km route over hilly terrain at a brisk pace with a light pack.
Base MET for hilly terrain is 5.0. The brisk pace multiplier is 1.2 and the light pack multiplier is 1.06, giving an effective MET of about 6.4. The assumed speed is 3.4 × 1.15 ≈ 3.9 km/h. The estimate works out to roughly 120 kcal per km and about 600 kcal for the whole route, with a moving time around 77 minutes.
Reference MET Values
The table below shows the base MET and assumed moving speed used for each terrain category.
| Terrain | Base MET | Assumed speed (km/h) |
|---|---|---|
| Easy paths & urban parks | 3.2 | 4.5 |
| Moderate woodland & farm tracks | 4.0 | 4.0 |
| Hilly rolling countryside | 5.0 | 3.4 |
| Rugged off-trail & rocky | 5.8 | 2.8 |
| Intensive searching / orienteering | 7.0 | 4.0 |
Pace multipliers are 0.8 for a leisurely outing, 1.0 for steady walking, and 1.2 for a brisk hike. Load multipliers are 1.0 with no pack, 1.06 for a light pack, 1.16 for a heavy pack, and 1.28 for a full expedition load.
Factors Affecting Accuracy
- Fitness and body composition: Fit walkers often use less energy at the same speed, while a higher body mass generally raises the calorie cost.
- Trail conditions: Mud, loose gravel, snow, and fallen branches make every step harder than the terrain category alone suggests.
- Search time: Standing still while reading the GPS, checking hints, or hunting under tree roots adds time but not much distance. A slow-moving hunt can burn calories at a lower per-km rate because your speed drops.
- Backpack fit: A well-packed, hip-belted pack is easier to carry than the same weight swinging loosely.
Quick Tips for Geocachers
- Record your route with a GPS or phone app to get the distance actually walked instead of planned kilometres.
- Use the Geocaching terrain rating (T-rating) only as a rough guide; local rainfall and recent logging can change a trail more than the rating suggests.
- Take water and a snack for routes longer than a few kilometres, and eat something after the hunt if your goal includes recovery.
- If you carry the same pack on every outing, log it once and keep it selected so your estimates stay consistent.
Frequently Asked Questions
Does geocaching really burn enough calories to matter? Yes. A few hours of searching typically burns several hundred kilocalories, which can be a meaningful part of an active day, especially on hilly or rugged terrain.
Why does the calculator multiply by body weight? Energy expenditure scales closely with body mass: moving a heavier body requires more energy for the same distance, which is why the MET formula includes body weight in kilograms.
Can I use this calculator for other outdoor activities? The structure works for hiking and bushwalking generally, though the terrain categories and speed assumptions are tuned to geocaching-style movement with pauses for searching.
The MET figures used here are consistent with the Compendium of Physical Activities and the Wikipedia article on metabolic equivalents. For general activity guidance, see the CDC physical activity basics. For geocaching safety and etiquette, the official Geocaching site is a good starting point.
