Add sessions to KnotNow
Pick the route that fits you. After you sign in, all three paths use the same full debrief — legs, VMG, foiling, turn-by-turn, and more. Free includes up to 3 loggable sessions (Strava imports count toward that limit).
Strava (easiest)
Best if your wing, windsurf, or sail sessions are already on Strava. No GPX export step.
- Sign in to KnotNow.
- Open Sessions — when you have no activities yet, tap Connect with Strava on the dashboard, or connect from your account area after you are in.
- Authorize Strava, then tap Import historical sessions from Strava (up to 8 per tap). Each tap checks your 150 newest Strava activities for wind and foil sports (wing, windsurf, kite, sail — not surf or SUP). Tag wing sessions as Windsurf or Sail on Strava if they appear as Workout.
Strava imports count toward your 3 free loggable sessions. Pro unlocks unlimited logbook and Strava import. See pricing.
GPX or TCX file
For Garmin, Apple Watch, COROS, or any tracker that exports activity files.
- Formats: .gpx or .tcx
- Size: Up to 10 MB per file
After sign-in, drop a file on the Sessions dashboard empty state, or use the upload flow when you are in the app.
Exporting from Garmin Connect
If your activity did not sync automatically, export it manually:
- Sign in to Garmin Connect on the web.
- Open the activity you want to export.
- Click the gear icon (⚙️) or More menu.
- Select Export to GPX or Export to TCX.
- Save the file, then upload it in KnotNow after you are signed in.
You can also export from the Garmin Connect app: open the activity → Share → Export.
Exporting from Apple Watch / iPhone
Activities recorded with the Workout app can be exported via third-party apps:
- HealthFit (iOS) – Export workouts as GPX or TCX from the Health app.
- RunGap (iOS) – Syncs workouts and can export to GPX/TCX.
Or connect Strava and use Strava import above instead of manual export.
Record on the KnotNow iOS app
Record on the water with GPS, wind, and session metadata in the KnotNow app. When you are back online, the session syncs to your logbook with the same analytics as GPX and Strava.
Open record in the iOS app (sign in required).
Garmin watch app
KnotNow also offers a Garmin watch app for recording and race timing on compatible watches.
Finding files on your Garmin device (advanced)
If you have the device connected via USB and need to copy files directly:
Mac
- Connect your Garmin device with the charging cable.
- Open the Garmin device drive in Finder.
- Go to Garmin → Activity.
- Copy the .fit files. Convert to GPX/TCX via Garmin Connect (export from the activity page) or a converter tool.
Devices with on-board music or MTP may not show as a drive on Mac. Use Garmin Connect export instead.
Windows
- Connect your Garmin device with the charging cable.
- Open File Explorer and find your Garmin drive under This PC.
- Open Garmin → Activity.
- Copy the .fit files. Convert to GPX/TCX via Garmin Connect (export from the activity page) or a converter tool.
