Hiking Time Formula
HT = 19.5*D + 30*E/1000
Variables:
- HT is the Hiking Time (minutes)
- D (miles) is the total distance
- E (ft) is the total elevation gain
To calculate Hiking Time, multiply the distance in miles by 19.5, then add 30 times the elevation gain (in feet) divided by 1000.
Assumptions & Limitations
- This calculator uses a Naismith-style pace rule (as shown in the formula above) and applies the selected condition factor to adjust the estimate.
- It estimates time from distance and ascent only; it does not account for descent effects, technical terrain (scrambling/climbing), off-trail navigation, altitude acclimatization, required rest beyond planned breaks, or trail-specific hazards.
For official hiking safety and pacing guidance, check local park/forest service recommendations and current weather/daylight forecasts.
How to Calculate Hiking Time?
The following steps outline how to calculate the Hiking Time.
- First, determine the total distance.
- Next, determine the total elevation.
- Next, gather the formula from above = HT = 19.5*D + 30*E/1000.
- Finally, calculate the Hiking Time.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
total distance = 5 miles
total elevation gain = 10,000 ft
Hiking Time = 19.5*5 + 30*(10000/1000) = 397.5 minutes (about 6 hours 38 minutes).
FAQ
How accurate is the Hiking Time Calculator?
The Hiking Time Calculator provides an estimate based on distance, elevation gain, and the selected condition factor. Actual hiking times can vary with terrain, weather, navigation complexity, pack weight, and fitness.
Can I use the Hiking Time Calculator for any trail?
It works best for well-marked, non-technical hikes where distance and elevation gain are known. For technical routes (scrambling/climbing), deep snow travel, off-trail navigation, high altitude, or extreme heat/cold, use additional planning and local guidance.
What factors can affect my hiking time besides distance and elevation?
Several factors can affect hiking time, including weather conditions, trail surface and complexity, your fitness level, pack weight, navigation/route-finding, and breaks taken during the hike.
Is there a way to improve hiking time?
Improving your physical fitness, especially cardiovascular and leg strength, can reduce hiking times. Practicing good pacing, strengthening downhill tolerance, and carrying an appropriate load can also help.
