Split an activity in two
Your file never leaves your device — conversion happens here in your browser.
It's an easy mistake: you finish a hike, forget to stop the recording, drive to a second trailhead, and start hiking again — and now you have one file containing two completely separate activities stitched together by a car journey in between. Uploading that as-is to Strava or Garmin Connect gives you one nonsensical activity with a huge speed spike in the middle and combined stats that don't represent either hike accurately. The fix isn't to trim, since you want to keep both halves, just as two separate files instead of one. FitFileHub's split tool cuts a single recording into two files at a point you choose. You can pick the split point three ways: by elapsed time, by distance along the route, or — usually the fastest way to find the exact right spot — by clicking the point on a map showing the full route. That last option is particularly useful for the drove-between-two-hikes case, since the transition is usually obvious as a straight line jump on the map where the recording clearly stopped tracking foot movement. Everything before the split point becomes the first file, everything after becomes the second, and each keeps its own timestamps, elevation, and any heart rate or cadence data exactly as originally recorded — nothing is recalculated or altered, the file is just divided in two. Both resulting files download separately, ready to upload as the two distinct activities they actually were. This is the mirror-image tool to merging: split when one file should be two, merge when multiple files should be one. As with everything else on FitFileHub, splitting happens entirely in your browser, so the route data in either half is never sent to a server. Free for files up to 25 MB, three at a time.
Questions
Does splitting recalculate stats like distance or pace for each half?
No — each resulting file keeps the original recorded data for its points exactly as-is. Distance and pace for each half are simply whatever those points naturally add up to, nothing is recalculated or estimated.
What's the easiest way to find the exact split point?
Clicking directly on the map where your route shows the transition — like a straight line where you drove between two trailheads — is usually faster and more accurate than guessing a time or distance value.
Can I split a file into more than two pieces?
Each split produces two files from one. To get three or more pieces, split the output file again at your next chosen point.
Will the two split files have accurate individual start times when uploaded?
Yes — each file retains the original timestamps of its points, so the second file's start time reflects exactly when that portion of the recording began, not when you split it.
