How to Split a GPX File Into Multiple Tracks

A single multi-day tour or a forgotten-to-stop recording often ends up as one giant GPX file. Splitting it makes the data usable in fitness apps, route planners, and shareable maps.

Why split?

• Per day for a multi-day tour so each day shows up as its own activity.
• Per segment when GPS dropped out mid-trip and the file has a teleport line.
• Per activity if you accidentally combined a ride and a hike in one recording.

The browser approach

The GPX Viewer & Editor supports splitting:

1. Drop in the GPX file.
2. Review the rendered track and stats.
3. Choose Split and pick the number of segments.
4. Download each as a separate GPX with original timestamps preserved.

When to use time-based vs segment-based splits

• Time-based is best for multi-day tours — split at midnight UTC or local time.
• Segment-based is best for fixing dropouts — split at the gap.
• Distance-based is best for long rides you want to break into stages.

The editor supports equal-length splits and manual cut points.

After splitting

• Re-upload each piece to Strava, Komoot, or your watch's web portal.
• Use the GPX Photo Sync tool to match photos to the right segment by timestamp.
• Or convert each segment to KML with the KML ↔ GPX Converter for Google Earth viewing.
