How to Fix a Workout When You Forgot to Resume a Paused Watch
By Roy Lachica on . Last updated .
It has happened to almost every runner: you hit pause at a traffic light, a water stop, or the start of a warm-up — and then you forget to press the resume button before you start running again. You only notice the mistake at the end of the session when the GPS track shows a sudden jump, the distance is too short, or there is a long unexplained gap in the middle of your route. The good news is that you can fix it with GpxFix. GpxFix gives you several tools to adjust the GPX file and produce an accurate, complete workout record.
Understanding what actually went wrong
When a GPS watch is paused it stops recording track points. Once you resume (or forget to resume and the watch auto-resumes) the track continues from a completely different location in time and space. The result in the GPX file is one of the following:
- A missing segment: a section of the route simply does not exist in the file — the track jumps from the pause location directly to wherever the watch restarted.
- A GPS spike / straight-line artefact: the map draws an impossible straight line across the gap, inflating or deflating distance, speed and elevation statistics.
- A time gap: the timestamps in the GPX jump forward by the duration of the missing section, which distorts pace, heart-rate, and power graphs on Strava.
Assessing the damage before you fix anything
Open your exported GPX file in GpxFix and use the interactive timeline slider under the map. Look for the point where the track jumps or the straight-line artefact begins — make a note of the track-point index numbers around the gap. This will be important when you apply fixes later.
Option 1 — Restore the missing segment from the return path (Restore from self)
If your run was an out-and-back route this is often the best fix. GpxFix can reconstruct the missing outbound segment by mirroring the recorded return path over the gap.
Workflow:
- Open the GPX file in GpxFix.
- Select the Restore segment - Restore from lap or roundtrip option and click 'Restore'.
- GpxFix now mirrors the return path into the gap, or the other way around, producing a smooth, continuous track.
- Preview the result on the map, then export or upload to Strava.
Option 2 — Restore the missing segment from a reference file
If you have a second GPX file that covers the same route — a previous run on the same path, a friend's activity, or a planned route file — GpxFix can use it to fill in the gap precisely.
Workflow:
- Open the broken GPX file in GpxFix as your primary file.
- Load the reference GPX file into the second-file slot.
- Select the Restore segment - Restore from reference GPX file operation.
- GpxFix extracts the matching segment from the reference file and inserts it into the gap, interpolating timestamps so the pace graph stays realistic.
- Preview, export, and upload to Strava.
Option 3 — Restore segment from time gap
Workflow:
- Use the timeline slider to identify approximate track-point index before or after the jump.
- Enter the track number and click the 'Restore time gaps'-button.
- GpxFix will now add missing track points and provide estimate values for HR, cadence etc.
- The created segment will now be in a straight line, and unless you actually ran in a straight line you probably want to move the track points using the Edit coordinates feature..
Option 4 — Edit individual track points by moving them to the correct location
Often you can move track points before and after the pause around so that they match the path where you did not record because of the pause. Beware that this will usually not be a perfect fix. The points moved will be in the right place but the timestamps will still reflect the time of the original recording, so pace graphs may look strange. However, if you only care about the map and distance being correct, this can be a quick way to clean up a few misplaced points without needing to reconstruct an entire section.
Workflow:
- Use the timeline slider to locate the track-point index of each misplaced point.
- Zoom in on the map where the issue is visible. Click the Edit coordinates button in GpxFix.
- Move the track points around to match where you actually travelled.
- Repeat for any other misplaced points around the gap.
- Preview the corrected track on the map, then export and upload to Strava.
Choosing the right fix — a quick decision guide
| Situation | Recommended option |
|---|---|
| Out-and-back run, gap overlaps the return path | Option 1 — Restore from self |
| You have a reference file or planned route for the same path | Option 2 — Restore from reference |
| Gap is short | Option 3 — Restore segment from time gap |
| Some points are slightly off the real route and need repositioning | Option 4 — Edit individual track points |
After fixing — what to expect on Strava
Once you export the repaired GPX and upload it to Strava:
- The map will show the full, continuous route without jumps or straight-line artefacts.
- Distance, pace and elevation graphs will reflect the corrected data.
- Moving time will be accurate if you also applied a time fix.
- Segment times may change if the restored segment covers a known Strava segment — that is generally a good thing because your effort will now be correctly recorded.
Tips to avoid the problem in future
- Enable auto-resume: some modern GPS watches (Garmin, Polar, Suunto) have an auto-pause and auto-resume setting — enable it so the watch restarts automatically when you start moving again.
- Check the screen before you run: glance at the watch face to confirm it shows a recording state (typically a blinking dot or running icon) before you start your effort.
- Use the live-map check: after a traffic stop, quickly swipe to the map screen to confirm the track line is being drawn from your current position.
- Keep the original file: always work on a copy of the exported GPX. Store the original somewhere safe in case you want to compare results or try a different repair strategy.
- Just stop pausing your watch. Just let it record what you were doing.
Closing thoughts
Forgetting to resume a paused watch is one of the most common GPS recording mistakes, but it is far from fatal. Whether you need to reconstruct the missing route from a reference file, mirror your own return path, stitch two separate recordings together, or simply trim out the jump, GpxFix has a dedicated tool for each scenario. A few minutes of editing is all it takes to turn a broken recording into an accurate, presentable Strava activity. Give it a try.
