Hiking Time Calculator

Estimate how long a hike will take based on distance, elevation gain, and your pace.

Hiking Time Calculator

Estimate your hiking time based on distance, elevation gain, and your personal pace using Naismith's Rule.

Understanding the Inputs

Distance & Elevation Gain

These are the two most critical factors for estimating hiking time. Elevation gain often has a greater impact on your time than horizontal distance.

Pace

This adjusts the formula based on your fitness level. Be honest with your self-assessment. If you're new to hiking or carrying a heavy pack, choose a slower pace.

Methodology

This calculator uses a modified version of **Naismith's Rule**, a classic formula developed in 1892 by Scottish mountaineer William W. Naismith. The rule states that you should allow:

  • 1 hour for every 3 miles (or 5 km) of horizontal distance.
  • 1 additional hour for every 2,000 feet (or 600 meters) of ascent.

Our calculator adjusts the base pace according to your selected fitness level and then adds the time calculated for the elevation gain to arrive at a total estimated moving time.

The Art and Science of Trail Timing

A Hiker's Guide to Accurately Estimating Trail Time

One of the most important skills for any hiker is the ability to accurately estimate how long a trail will take. It's a matter of safety—ensuring you have enough daylight—and enjoyment, allowing you to properly pace yourself and plan for breaks. A simple mileage calculation is often misleading in the mountains. This guide explores the time-tested formulas for estimating hiking time, the factors that influence your pace, and how to use this knowledge to plan safer, more enjoyable hikes.

Beyond Simple Mileage: The Importance of Elevation

For walking on flat ground, a simple `Time = Distance / Speed` works well. But in hiking, vertical distance (elevation gain) is just as, if not more, important than horizontal distance. Climbing 1,000 feet can be as strenuous as walking several miles on a flat path. Any reliable estimation method must account for both.

Book Time vs. Real Time: Don't Forget the Breaks!

The time estimated by our calculator is often called "book time" or "moving time." This is the time you spend with your feet on the trail. It does **not** include:

  • Water and snack breaks
  • Lunch stops
  • Time spent taking photos
  • Rest stops to catch your breath on a steep section
  • Layering and de-layering clothing

A good rule of thumb is to add **20-30%** to your calculated moving time to get a more realistic total trip time. For a calculated 4-hour hike, it's wise to budget at least 5 hours from trailhead to trailhead.

Summary

The Hiking Time Calculator is an essential safety and planning tool for any outdoor enthusiast. By using a modified version of Naismith's Rule, it provides a realistic estimate of your "moving time" by considering both the horizontal distance and, crucially, the vertical elevation gain of your intended route. This allows you to plan your day, know when to turn around, and ensure you have enough daylight for a safe and enjoyable adventure.
