How to Use This Calculator

Enter Total distance (km), Elevation gain (m), and Checkpoints.
Set Terrain Difficulty, Groomed trail, and Light off-trail.
Adjust Mixed off-trail, Rough terrain as needed.
Review the Estimated time (hrs) result.
Use Avg pace (min/km) and Avg speed (km/h) to inform your decision.

How the result changes with Total distance (km)

Total distance (km)	Estimated time (hrs)
50	18.48
175	58.13
325	105.72
450	145.37

What each input means

Total distance (km): Total course distance in kilometers.
Elevation gain (m): Total vertical ascent in meters.
Checkpoints: Number of navigation checkpoints on the course.
Terrain Difficulty: Terrain conditions on the course.
Fitness Level: Your athletic fitness level.
Pack weight (kg): Total weight of gear and supplies carried.

What each result means

Estimated time (hrs): Total estimated time to complete the course.
Avg pace (min/km): Average pace including terrain and navigation.
Avg speed (km/h): Average speed over the full course.
Avg leg time (min): Average time between checkpoints.
Navigation overhead (min): Total time spent on map reading at checkpoints.
Terrain slowdown (%): Percentage slowdown from terrain difficulty.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Total distance (km) = 25, Elevation gain (m) = 800, Checkpoints = 6, Terrain Difficulty = 3 = 6 input(s) provided
Calculate Estimated time
Estimated time = (baseTimeHrs + climbTimeHrs) * terrainMultiplier * fitnessMultiplier * weight...
10.55 = 10.55
Calculate Avg pace
Avg pace = (rawTimeHrs * 60) / distanceKm
25.3 = 25.3
Calculate Avg speed
Avg speed = distanceKm / rawTimeHrs
2.4 = 2.4
