My 9.0 mile run this morning with Apple Watch Ultra recorded 477 ft of gain. Strava is showing 3,395 ft of gain. There is an option to correct/adjust elevation on the website and app that calculates a much more realistic elevation gain. Strava seems to be incorrectly reading the elevation data from apple watch workouts.

Thanks a lot for your kind response awareagle!

I went through the app as well as the web site, but unfortunately I could not find the option you mentioned, neither in the settings, nor in the individual trainings.

would you mind sharing in more detail, where to find this option?

Thanks again!

On the website, open an activity. On the left side is a three dot button. Click that and there should be a correct elevation option.

In the app there should be the same option under the three dot icon in the dot right when looking at an activity.

Great!

The calculated altitude is a far more realistic result now.

Thanks again for your kind and fast support!

Will this fix the issue for future activities? 

Hi, I’ve noticed the same issue, and it’s incredibly frustrating to see completely inaccurate elevation gain data on the Strava app when using an Apple Watch. What drives me crazy is that the elevation gain recorded on the Apple Fitness app is accurate and matches the data from my wife’s Garmin.

Strava, please consider using the elevation data from the Fitness app directly, without altering it unnecessarily. I understand you can adjust elevation through the Strava app using its map, but even that method isn’t entirely reliable.

This is still an issue. I shouldn’t have to correct the elevation for every activity since the correct elevation is already being provided by Apple.

This needs to be elevated at Apple.  Apple is not sharing how it corrects barometric altimeter raw data for elevation gain calculation with other 3rd party.  FIT file Apple sends uncorrected raw barometric altimeter data.  This was feedback I got from both Strava and Wahoo.

When I contacted Apple support today, they weren’t aware of this problem but understood the problem when I supplied screen shots of Apple fitness workout details vs Strava/Wahoo/Komoot/Garmin imported workout details showing almost double elevation gains.

Apple support sent me “Apple Profile for Advanced Logging” for HealthKit and asked me to use. profile during next hiking/cycling with significant elevation gain.  

More people raise this issue with Apple, faster it will be corrected.
