How is total distance calculated?

Distance is the sum of great-circle (Haversine) distances between each pair of consecutive track points using an Earth radius of 6,371 km, which is accurate over the short hops in a GPS log.

How are ascent and descent measured?

The tool walks the elevation series and adds every positive step to the gain total and every negative step to the loss total. A small smoothing threshold ignores tiny jitters so GPS noise does not inflate the climb.

What does average grade mean here?

Average grade is total elevation gain divided by total horizontal distance, expressed as a percent — a rough measure of how steep the route is overall.

How is pace computed?

If the points carry timestamps, moving time is the elapsed time between the first and last point, and pace is that time divided by distance, shown in minutes per kilometre.

GPX Elevation & Distance Stats

Get distance and elevation stats from a GPX file

This tool reads a GPX track and computes the numbers that matter to hikers, runners and cyclists: total distance, cumulative elevation gain and loss, highest and lowest altitude, average grade, and — if the file has timestamps — moving time and pace. It also draws an elevation profile.

How it works

Track points are parsed with the browser’s DOMParser. Distance is the running sum of Haversine great-circle distances between consecutive points. Elevation gain adds up every upward step in the ele series and loss adds up every downward step; a small threshold (the default ignores changes under a couple of metres) suppresses GPS noise so the climb total stays realistic. Average grade is gain over distance as a percent. If timestamps are present, moving time is the span from first to last point and pace is time per kilometre.

Example

For a short loop that climbs from 12 m to 25 m and returns, the tool reports a few hundred metres of distance, roughly 13 m of gain and 13 m of loss, a max of 25 m and a min of 12 m, and — with timestamps — a pace in minutes per kilometre. Everything is computed locally; nothing is uploaded.
