About this calculator
Estimate how long a hike will take based on distance, elevation gain, and your pace using the Naismith's Rule method.
Frequently Asked Questions
What is Naismith's Rule?
It's a formula used to estimate hiking time by allowing one hour per 3 miles of distance, plus extra time for elevation gain, typically 1 hour per 2,000 feet climbed.
Does this account for rest breaks?
No, this estimate covers moving time only. Add extra time for breaks, photos, snacks, or difficult terrain.
Why does elevation gain matter so much?
Climbing steep terrain slows your pace significantly compared to flat trails, so elevation gain is factored in separately from distance.
