Hiking Time Estimator
Plan your day on the trail with Naismith's classic hiking time formula. Enter the total distance and elevation gain to estimate how long it will take a fit hiker to complete the route, then adjust for rest stops, rough terrain, or group pace.
Times are estimates; adjust for fitness, weather, and trail conditions.
Examples
- 10 km trail with 600 m ascent ⇒ 3.0 hours of hiking time
- 14 km ridge walk with 900 m ascent ⇒ 4.3 hours of hiking time
- 8 km forest loop with 200 m ascent ⇒ 1.9 hours of hiking time
FAQ
What is Naismith's rule?
It's a time-tested guideline from 1892 that combines distance and elevation gain to approximate total hiking time.
Does terrain matter?
Absolutely. Rocky footing, deep snow, or off-trail travel can slow progress dramatically, so add extra time.
Is descent included?
Traditional Naismith's rule only accounts for climb. Add 5–10 minutes per 100 m of steep descent if the trail is technical or slippery.
Can I use miles and feet?
Yes—convert miles to kilometers (×1.60934) and feet to meters (×0.3048) before entering the values.
How should groups plan breaks?
Add 10–15 minutes every 90 minutes for snacks, photos, or navigation checks so your itinerary reflects a realistic pace.
Additional Information
- Naismith's rule assumes 5 km/h on level ground plus one extra hour for every 600 m (2,000 ft) of ascent.
- Steep descents, heavy packs, heat, snow, or technical terrain can add significant time—plan conservative buffers.
- Experienced hikers often apply Tranter's corrections by adding 10 minutes per 300 m of descent for rugged routes.
