How to Use This Calculator
  1. Find your portage distance in rods from your map or trail sign (1 rod = 16.5 ft; 80 rods ≈ 0.25 miles).
  2. Enter your boat weight in lbs — canoes typically range from 35 to 75 lbs.
  3. Input total gear weight in lbs for all packs and equipment you must carry.
  4. Select the terrain difficulty: flat/groomed trail up through steep/rocky or bushwhack.
  5. Choose your fitness level to calibrate walking speed under load.
  6. Read Total Portage Time, Number of Trips (1 = single carry, 3 = double portage), and Calories Burned to schedule your day.

What each input means

Portage distance (rods)
Distance in rods (1 rod = 16.5 ft). 80 rods ≈ 0.25 miles. Check BWCA maps for distances.
Boat weight (lbs)
Weight of your canoe or kayak.
Gear weight (lbs)
Total weight of packs, food, and equipment to carry.
Terrain Difficulty
Portage trail conditions.
Fitness Level
Your physical fitness level.

What each result means

Total portage time (minutes)
Estimated time including all trips if double-portaging.
Number of trips across
1 = single carry, 3 = double portage (carry-return-carry).
Total distance walked (ft)
Actual walking distance including return trips.
Loaded walking speed (mph)
Estimated speed while carrying gear.
Calories burned
Estimated caloric expenditure for the portage.
Effort score (0-100)
Overall portage difficulty. Higher = more demanding.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Portage distance (rods) = 80, Boat weight (lbs) = 65, Gear weight (lbs) = 50, Terrain Difficulty = 2 = 5 input(s) provided
  2. Calculate Total portage time
    Total portage time = totalTimeHrs * 60
    27 = 27
  3. Calculate Number of trips across
    3 = 3
  4. Calculate Total distance walked
    Total distance walked = distanceFt * numberOfTrips
    3960 = 3960
