If you forgot your Stryd on a run but did a similar run in the past, you can complete your running record. At this time, you cannot import any files without Power Data or create a manual entry in PowerCenter, but you can copy an old run.

1. Export your old run to your computer.

2. Open fitfiletools.com and launch Time Adjuster.

3. Upload your old run and select the date of your recent run where you forgot your Stryd.

4. Save the file to your computer, and upload it into PowerCenter.

If you want to change the date for a run or duplicate a run to add it to a different day, you can do this with a tool called FitFileTools.com.

Export the FIT file from PowerCenter, and import the file into FitFileTools.com. There is a tool called Time Adjuster, which allows you to set the start time and date of your run. After you change the date of your run, download it to your computer and import it again into PowerCenter.
