Polar Heart Rate Monitor: Integrating with Strava for Enhanced Training

By Hart 9 min read

Using a Polar heart rate monitor with Strava involves connecting the HRM to a compatible Polar or third-party device/app that records the data, which then automatically syncs to Strava for analysis.

How do I use Polar heart rate monitor on Strava?

Integrating your Polar heart rate monitor (HRM) with Strava primarily involves connecting your Polar device or a third-party recording app/device (that receives data from your Polar HRM) to Strava, rather than directly connecting the Polar HRM to the Strava mobile app for live data capture during activity.

Understanding Heart Rate Training & Its Value on Strava

Heart rate monitoring is a cornerstone of effective endurance and fitness training, offering objective insights into your body's response to exercise. By tracking your heart rate, you can:

  • Optimize Training Intensity: Ensure you're training within specific heart rate zones (e.g., aerobic, anaerobic) to achieve targeted physiological adaptations, whether it's building endurance, improving speed, or burning fat.
  • Monitor Recovery: Observe your heart rate variability (HRV) and resting heart rate trends to gauge recovery status and prevent overtraining.
  • Track Progress: See how your heart rate responds to similar efforts over time, indicating improvements in cardiovascular fitness.
  • Enhance Safety: Stay within safe heart rate limits, particularly for individuals with pre-existing conditions or those new to exercise.

When integrated with Strava, this rich heart rate data transforms your activity logs from mere routes and times into comprehensive performance analyses. Strava's platform uses heart rate data to calculate Relative Effort, a proprietary metric that quantifies the physiological cost of your workout, allowing for meaningful comparisons across different activities and over time. It also enables detailed zone analysis, helping you visualize where you spent your time during a session and how it aligns with your training goals.

Polar HRMs: A Quick Overview of Compatibility

Polar has long been a leader in heart rate technology, known for its accuracy and reliability. Modern Polar HRMs, including chest straps like the Polar H10 and armbands like the Polar Verity Sense, primarily utilize Bluetooth Low Energy (BLE), also known as Bluetooth Smart. This is the critical technology that allows them to connect wirelessly to a wide range of compatible devices and apps.

Key Polar HRM Types:

  • Chest Straps (e.g., Polar H10, H9): Generally considered the gold standard for accuracy due to their proximity to the heart's electrical signals. They are robust and offer excellent connectivity.
  • Optical Armbands (e.g., Polar Verity Sense, OH1): Offer convenience and comfort by measuring heart rate from blood flow in the forearm or upper arm using optical sensors. While generally very accurate, they can sometimes be more susceptible to movement artifact.
  • GPS Watches with Integrated HR (e.g., Polar Vantage, Grit X, Ignite series): These devices have built-in optical heart rate sensors and can also pair with external Polar HRMs (like the H10) for enhanced accuracy during specific activities.

For seamless integration with Strava, the most important factor is that your Polar HRM supports Bluetooth Smart (BLE), which virtually all current Polar models do. This allows them to pair with smartphones, GPS watches, cycling computers, and fitness apps.

Connecting Your Polar HRM to Strava (Clarification & Methods)

It's crucial to understand a common misconception: The Strava mobile app itself typically does not directly connect to external Bluetooth HRMs for live heart rate display during an activity recording. While some older versions or specific Android configurations might have offered limited direct sensor support, Strava's primary role is as a data aggregation and analysis platform.

Therefore, the main methods to "use" your Polar HRM on Strava involve an intermediary device or app that does record the heart rate data, which then syncs with Strava.

This is the most common and reliable method if you own a Polar GPS watch or computer.

  1. Pair Your Polar HRM with Your Polar Watch/Device:

    • Ensure your Polar HRM (e.g., H10 chest strap) is worn correctly and active.
    • On your Polar watch (e.g., Vantage M2, Grit X Pro), navigate to Settings > General settings > Pair and sync > Pair other device.
    • Select your Polar HRM from the list of detected devices. The watch will confirm the pairing.
    • Note: If you're using a Polar watch, its built-in optical HR sensor will be used by default unless an external sensor is paired and active.
  2. Record Your Activity with Your Polar Device:

    • Start your workout as usual on your Polar watch or cycling computer. It will automatically record your heart rate from the paired Polar HRM.
  3. Sync Your Polar Device to Polar Flow:

    • After your workout, sync your Polar device with the Polar Flow app on your smartphone or the Polar Flow web service via your computer. This typically happens automatically when your device is near your phone with Bluetooth enabled, or when connected via USB to your computer.
  4. Connect Polar Flow to Strava:

    • This is a one-time setup:
      • Open the Polar Flow web service (flow.polar.com) in a web browser.
      • Go to Settings > Partners.
      • Find Strava in the list and click "Connect."
      • You will be redirected to Strava to authorize the connection. Grant Polar Flow permission to upload activities to Strava.
    • Once connected, all future activities synced from your Polar device to Polar Flow will automatically upload to Strava, including your detailed heart rate data.

Method 2: Connecting via a Third-Party GPS Device or Fitness App

Many popular GPS cycling computers, running watches (non-Polar brands), and indoor fitness apps can directly connect to Polar Bluetooth HRMs.

  1. Pair Your Polar HRM with the Third-Party Device/App:

    • For GPS Computers/Watches (e.g., Garmin, Wahoo, Hammerhead):
      • Wear your Polar HRM.
      • On your device, navigate to Sensors > Add Sensor (or similar path).
      • Select "Heart Rate" and allow the device to scan for your Polar HRM.
      • Once detected, select it to pair.
    • For Fitness Apps (e.g., Zwift, Peloton, TrainerRoad, etc.):
      • Open the app and look for a "Sensors," "Connect Devices," or "Pair Devices" option.
      • Ensure Bluetooth is enabled on your smartphone/tablet/computer.
      • Select "Heart Rate" and choose your Polar HRM from the list of detected Bluetooth devices.
  2. Record Your Activity with the Third-Party Device/App:

    • Start your workout using the third-party device or app. It will now display and record your heart rate from your Polar HRM.
  3. Ensure Third-Party Device/App is Synced to Strava:

    • Most popular fitness ecosystems (Garmin Connect, Wahoo ELEMNT, Zwift, etc.) offer direct integration with Strava.
    • One-time setup: Go into the settings of the respective app/platform (e.g., Garmin Connect app, Zwift settings) and find the "Connected Apps" or "Third-Party Connections" section. Connect it to your Strava account.
    • After this, activities recorded with that device/app will automatically upload to Strava, carrying your Polar HRM data with them.
