GPXFIT

Compare Routes

The Compare Routes tool allows you to compare 2-3 GPX or FIT files side-by-side. Overlay routes on a map, compare elevation profiles, and see detailed statistics comparisons.

How to Use

  1. Load a file in GPXFIT (this becomes File 1)
  2. Click the "Compare Routes" button
  3. Click "Add File" to upload a second file for comparison
  4. Optionally add a third file (maximum 3 files)
  5. View the overlaid routes, charts, and statistics

Features

Route Overlay

All routes are displayed overlaid on a single map view with different colors:

  • File 1 (Blue) - Your currently loaded file
  • File 2 (Green) - First comparison file
  • File 3 (Orange) - Second comparison file (optional)

Elevation Chart

Elevation profiles for all files are overlaid on a single chart, making it easy to compare terrain. You can toggle additional metrics:

  • Elevation - Always displayed
  • Speed - Optional overlay
  • Heart Rate - Optional overlay (if data available)
  • Power - Optional overlay (if data available)
  • Cadence - Optional overlay (if data available)
  • Temperature - Optional overlay (if data available)

X-Axis Options

  • Distance - Compare based on distance traveled (default)
  • Time - Compare based on elapsed time (requires timestamps in all files)

Statistics Comparison Table

A detailed table shows key metrics with difference columns:

  • Distance - Total route distance
  • Duration - Total time (if available)
  • Ascent/Descent - Total climbing and descending
  • Max/Min Elevation - Elevation extremes
  • Average/Max Speed - Speed statistics
  • Sensor Data - HR, Power, Cadence (if available)

Difference Columns

The table shows differences between files:

  • Δ 1-2 - Difference between File 1 and File 2
  • Δ 1-3 - Difference between File 1 and File 3 (if present)

Differences are color-coded: green for better values, red for worse (context-dependent).

Use Cases

Comparing Different Attempts

Compare multiple rides or runs on the same route to see how your performance has changed over time.

Route Planning

Compare different route options to choose the best one based on distance, elevation, or terrain.

Device Comparison

Compare recordings from different GPS devices to identify tracking differences.

Before/After Analysis

Compare an original file with a modified version to see the effects of edits.

Notes

  • File 1 (the currently loaded file) cannot be removed
  • Files 2 and 3 can be added or removed as needed
  • Routes do not need to be identical - you can compare any files
  • Metrics are only shown if data is available in the files
  • The Time X-axis option is disabled if any file lacks timestamp data
