Question 1

How accurate is this calculator?

Accepted Answer

This is a planning estimate only. Your actual time can vary significantly based on many factors including trail conditions, unplanned stops, weather, current hydration and nutrition levels, and fatigue.

Question 2

How many past hikes should I upload?

Accepted Answer

No uploads are required. Manually enter distance and elevation and the calculator starts with a tuned Naismith-style estimate. Five to nine usable past hikes can start teaching it your pace and break behavior. Ten to nineteen can support uphill, downhill, and flat-terrain patterns when there is enough coverage on similar terrain. Twenty to forty-nine can support a higher-confidence personal estimate. Fifty or more unlocks similar-hike matching.

Question 3

What files help the calculator learn my pace?

Accepted Answer

Upload GPX files from completed hikes, not planned routes. They need timestamps so the calculator can learn how long you were moving and how much time you spent stopped. Files exported from AllTrails, Strava, Garmin, Gaia, COROS, Suunto, or Apple workouts usually work if they include time data.

Question 4

Does the calculator store my GPX files?

Accepted Answer

Uploaded GPX files are parsed for the current estimate, then the reusable save options only keep derived summaries. Saved profiles should not include raw GPX text, coordinates, timestamps, point lists, file names, or file contents.

Question 5

What is similar-hike matching?

Accepted Answer

It appears when there are at least 50 usable past hikes. It compares the route with past hikes that look similar. Manually entered routes use distance, climbing, and downhill. GPX routes can also use route profile details such as uphill/downhill/flat sections and turn density.

Question 6

When does the calculator show uphill, downhill, and flat-terrain insights?

Accepted Answer

Personalized terrain insights stay hidden until there is enough personal history available for that type of terrain. The current thresholds are early confidence at 5 miles and 5 activities, moderate confidence at 15 miles and 10 activities, and high confidence at 30 miles and 20 activities.

Question 7

How do saved calculator links work?

Accepted Answer

A private return link stores a compact encrypted result or derived profile in the URL. It can be opened on another device, but anyone with that link can open it. There is no account, database, revocation system, or short-link service in this version.

Question 8

Why show hiking time and stopped time separately?

Accepted Answer

Hiking pace and stopping habits are different. A person can hike steadily and still have a long day if they stop often for food, water, photos, route checks, pain, kids, dogs, or a group.

Question 9

What does the route effort rating mean?

Accepted Answer

The route effort rating is an early route-comparison aid based on distance, climbing, and downhill. When usable past hikes are loaded, the result can also compare that rating with your own hiking history. It is not a medical score, safety score, readiness score, or guarantee of how the hike will feel.
