Importing Your Activity History into Stride

Stride has two separate imports, and they do different jobs. The activity history import brings the rides, runs and swims themselves across from another platform, using FIT files or ZIP archives. The TrainingPeaks import brings the words across: the comments you and your coach wrote, your RPE, and how each session felt, onto activities that are already in Stride. You will often want both, in that order.

Supported File Types#

• FIT files (.fit or .fit.gz)
• Standard binary activity files from Garmin, Wahoo, Hammerhead, COROS, and most bike computers and watches.
• Each file represents a single activity.
• ZIP archives (.zip)
• Compressed folders containing multiple FIT files.
• Ideal for importing your full history in one go.

How to Import into Stride#

You can import either a single FIT file or a ZIP archive of many FIT files.

1. Go to Account in Stride.
2. Select Import Data.
3. Drag and drop your FIT or ZIP file onto the upload area, or click to browse your computer.
4. Watch the progress bar to see upload status.

Single FIT File#

• Processed immediately after upload.
• The activity appears in your activity list as soon as processing completes.

ZIP Archive#

• Queued and processed in the background. Large archives take a while, so you can close the page and come back.
• Activities appear in your calendar as they finish, rather than all at once.
• Stride reads the FIT and TCX entries and ignores everything else, so you can upload the archive exactly as your old platform gave it to you. GPX files are not imported as activities.

Duplicates are handled for you#

The usual worry about a bulk import is that it will double your history, because most of what is in a Garmin export has probably already synced to Stride through a connected account. It will not. Every incoming activity is checked against what you already have before anything is created.

• Matching — a workout starting within about half a minute of one you already have is treated as the same workout. The same ride arriving from two sources rarely resolves to exactly the same second, so the comparison allows for that drift.
• The better recording wins — when the two are the same workout, Stride keeps one activity and uses the richer file. A file you upload yourself is treated as the definitive recording, because uploading it is a deliberate "use this one" decision, so it supersedes a copy that arrived automatically rather than sitting alongside it.
• Re-uploading is safe — importing the same archive twice, or importing a Garmin export and a Strava export that cover the same years, will not leave you with two of anything. Your comments, RPE and feel survive too, since a merge updates the existing activity rather than replacing it.
• Recovery devices are matched differently — a WHOOP or Apple Health record of a workout is a separate recording of the same session rather than a copy of the same file, so it is matched by how far the two overlap in time, and a real device file always takes precedence.

Exporting from your current platform#

Every platform hides its export in a slightly different place, and most of them email you a link rather than downloading straight away. Request the export first, then come back when it arrives.

Wahoo, Hammerhead, COROS, Zwift and other head units#

Connect these in Integrations and new activities sync automatically. For older history, the simplest route is usually a Garmin or Strava export, since most head units have been uploading to one of those all along. If you have the original files on the device or in its companion app, you can upload them directly as FIT files or a ZIP. COROS is worth singling out: it only lets Stride read the last three months, so anything before that has to come from a file.

Bringing your TrainingPeaks comments, RPE and feel across#

Years of training leave behind more than numbers. The note you left after a session that fell apart, the reply your coach wrote the next morning, the effort you gave it out of ten: none of that lives in a FIT file, so no device sync will ever bring it across. This import does.

What it brings, and what it leaves alone#

It imports four things onto activities you already have in Stride:

• Your comments and your coach's, added to the activity's notes.
• The prescribed session description, where the activity has no description and no Stride workout attached.
• RPE, on the same 1 to 10 Borg scale Stride uses.
• Feel, converted onto Stride's scale.

It never creates activities, and it never touches your recorded data. Duration, distance, power, heart rate and training load stay exactly as Stride calculated them from your device file. TrainingPeaks' versions of those numbers are its own analysis of the same ride, so importing them would only put two answers where there should be one.

Review before anything is written#

Uploading does not import anything on its own. Stride reads the export, matches each workout against your activities, and shows you what it found. Only when you press the import button does it write. Four counts summarise the match:

• To import — matched an activity and has something new to add.
• Already there — matched, but the activity already carries everything the row offered.
• No match — nothing in Stride on that day for that sport. Usually a workout that never synced across. Import your activity history first and run this again.
• Needs a choice — two activities that day fit equally well, so Stride writes nothing rather than risk putting your note on the wrong one. Add these by hand on the activity itself.

How workouts are matched#

The export carries no device or file identifier, so there is nothing to join on directly. Stride matches on the day the workout sits on, then the sport, then how closely the duration, distance and title line up with the activity's. A workout type TrainingPeaks does not name precisely, such as Other or a race, is allowed to match any sport on its day. Rest days are skipped.

How RPE and feel convert#

RPE carries across unchanged, since both platforms use the modified Borg scale of 0 to 10. Feel does not: TrainingPeaks records it with 1 as the strongest you can report, and Stride records it with 5 as the best. So the scale is turned around and compressed, with the strongest rating becoming 5 and the weakest becoming 1.
