Indoor and outdoor cycling activities recorded with the Apple Workout app will include power and cadence data if those sensors are connected to the watch. Power and cadence data are displayed on the activity detail page within the mobile app and on the web.
Make sure you've allowed Strava to read power and cadence data by taking the following steps:
From your iPhone, go to Settings> Health > Data Access & Devices > Strava, then toggle all available options on.
Accept all health data permissions.
Accept the new permissions from Apple Health, even if you have previously connected with Health. Open Strava and tap the Settings icon, then Manage Apps & Devices > Health, and tap 'Connect with Health.' New activities will now display power and cadence if it's available in the file.
Please be aware that only activities recorded with the Apple Watch Workout app within the past 30 days can sync to Strava. Activities uploaded to the Health app from a third party will not sync to Strava.
FAQs
Why Aren't My Cadence and Power Data Displayed on Strava After I Synced My Cycling Activity From the Apple Fitness App?
To see cycling power and cadence information from HealthKit on your Strava app, you'll need iOS 17+, watchOS 10+, and Strava app version 403+. Please also ensure you've accepted the necessary data permissions by following the steps above, even if you've already done so.
What About Running Power and Cadence Data From Health?
Strava only supports running power data from HealthKit. We do not support cadence information at this time. To view power data for your running activities on the activity details page in the mobile app, ensure you have granted the necessary data permissions.
Power data will not be displayed on the web and will not be factored into an athlete's Fitness & Freshness or Power Curve.
