Combine multiple GPX or FIT files into a single track and download as GPX.
Add at least 2 files to merge
Merge stitches any number of GPX or FIT files into a single GPX track, ordered by timestamp with no gaps. It is the fix when a device split a ride across files, when you paused recording, or when you are joining stages of a multi-day route.
Drop all the files at once — order does not matter, they are sorted by GPS time — and download one continuous GPX, with heart rate, cadence, and elevation preserved where present.
When a GPS device paused or restarted mid-ride and made two files, when you exported separate morning and afternoon sessions, or when you are combining stages of a multi-day route into one track.
Yes. Merge accepts any mix of .gpx and .fit in the same batch — no conversion needed. The output is always GPX, the most universally compatible format.
No. All points across all files are sorted by GPS timestamp, so you can drop them in any order, all at once.
Heart rate, cadence, elevation, and speed are preserved from the source files where available, and the merge happens entirely in your browser — nothing is uploaded.
