Why it matters
A Better Way to Plan Backcountry Nutrition
Route planning is solved. Nutrition planning comes next.
Rules of Thumb Fall Short
"2 lbs of food per day" doesn't account for your body, your pack weight, or the 4,000 feet of elevation gain on Day 2.
Your Watch Is Wrong
Consumer wearables can be off by 27-93% for loaded hiking. They use flat-ground math that ignores pack weight, terrain, and grade.
The Stakes Are Real
Bonking on Day 3, losing 10+ lbs on a thru-hike, or carrying pounds of uneaten food. Getting nutrition wrong has consequences.
Stop Guessing Your Hiking Calories
Get science-backed calculations for your backcountry nutrition.
From Route to Meal Plan in One App
Draw your route, get your calorie targets, build your meal pack.
Plan Routes on 3D Terrain Maps
Draw routes with snap-to-trail, place waypoints, or import GPX files from your favorite planning tools. See distance, elevation gain, and moving time update as you build.
- Topographic maps with contour lines and hillshade
- Snap-to-trail routing or freehand drawing
- Import GPX files from any planning tool
- Public lands overlay with ownership boundaries
The Math Your Watch Can’t Do
Calorie needs spike on a steep climb and drop in a valley. MTNMetrics calculates metabolic rate segment by segment using the LCDA equation — peer-reviewed research from the U.S. Army.
- Total trip calories with confidence range
- Factors in pack weight, terrain type, and elevation
- Personalized to your body (weight, height, age, sex)
- Hiking vs. rest calorie breakdown
Every Day Gets Its Own Target
A 3-day trip isn't three identical days. Day 1 over the pass might need 3,700 calories. Day 2 along the valley only 2,300. MTNMetrics calculates each day based on the actual terrain you'll cover.
- Individual calorie targets per hiking day
- Elevation profile with daily segments
- Hiking vs. base calorie breakdown per day
- Moving time estimates per day
Build Your Meal Pack in Minutes
Stop agonizing over food lists. Browse trail-ready meals, filter by dietary needs, and build a pack that hits your calorie and macro targets — with every item tracked in real time.
- Curated food catalog with full nutrition data
- Filter by dietary needs (vegan, GF, dairy-free)
- Track calories, protein, fat, carbs, and pack weight
- Progress bar toward your trip calorie target
