Merge GPX, FIT and TCX files into one track

Recorded a ride in three parts because the battery died, or want a week of walks as one file? Drop the GPX, FIT or TCX files here (mixed is fine) and download one clean GPX track.

What it does

• Reads every track point from GPX, TCX and Garmin/Wahoo-style FIT files, plus GPX route points and waypoints.
• Damaged FIT files (cut off when a battery died or a device crashed) are repaired: every complete record is recovered.
• If every point has a timestamp, sorts the whole track by time, so the order you drop files in doesn't matter.
• Removes exact duplicates (same position and time), which appear when recordings overlap.
• Keeps elevation, time and heart rate. Counts points in and out so you can see nothing was lost.

The merged file is standard GPX 1.1 and imports into Strava, Garmin Connect, Komoot and most mapping apps. fileforge is not affiliated with any of them.
