Diagnosis

Let your Polar watch / sensor record once and fan out from there: Polar watch / sensor → Strava and Polar watch / sensor → TrainingPeaks. Trust Stryd for power and pace, Polar watch / sensor for the file — and turn off the Stryd PowerCenter auto-post to Strava so your feed and your coach each see exactly one run.

Data route

This is the fix: which connections to keep and which to switch off.

✅ Enable these

  • Stryd pod → Polar watch / sensor (power & pace)Best power/pace into your one file.
  • Polar watch / sensor → StravaOne run on your feed.
  • Polar watch / sensor → TrainingPeaksOne workout for your coach.

❌ Disable these

  • Stryd PowerCenter → StravaStryd PowerCenter auto-post duplicates the recorded run.

During the workout

Do start

  • Record the run on your Polar watch / sensor with Stryd paired for power and pace.

Don't start

  • Don't leave the Stryd app running its own session that auto-uploads.

Step-by-step setup

Account links

  1. Connect Polar watch / sensor to Strava.
  2. Connect Polar watch / sensor to TrainingPeaks (TrainingPeaks → Settings → Connect → Polar watch / sensor auto-sync).
  3. In the Stryd app, turn OFF auto-upload to Strava (Stryd → Settings → Connections → Strava).

Device settings

  1. Disable NATIVE running power so Strava shows Stryd power, not the wrist estimate.

During each workout

  1. Start an outdoor run on the Polar watch / sensor; Stryd supplies power and pace.

Verify it worked

  1. Confirm one run in Strava AND one in TrainingPeaks — both from your watch, with Stryd power.

⚠️ Duplicate-risk warnings

High risklands in Strava

Stryd PowerCenter and your watch both post to Strava → duplicate.

Fix: Turn off Stryd's Strava auto-post; keep the watch → Strava.

Medium risklands in TrainingPeaks

If TrainingPeaks pulls from BOTH Strava and your watch, your coach sees two.

Fix: Use a single TrainingPeaks source (the watch); disable any Strava → TrainingPeaks sync.

What data to trust

  • Trust Stryd podfor running power and pace.
  • Trust Polar watch / sensorfor the recorded file, distance and time.

You'll know it worked when…

Exactly one run in Strava and one in TrainingPeaks, both showing Stryd power — your coach sees a single clean workout.
