Hello @Pb111 and thank you for your post.
Sorry about the discrepancies between your activities as shown on another platform and Strava. We are two separate platforms with different calculations so certain aspects of your activity analysis may be different. We use our own calculation for pace and moving time based on the GPS data that is sent to us. This means that even though the elapsed time is the same, the moving time can be a bit different, which can cause differences in average speed/pace.
We feel confident that we are accurately representing your data, but are always working on improving our calculations and appreciate your feedback. You may want to search our support site for more information and discussions on this topic.
I’ve had the exact same issues using the Polar Verity armband.
I use WorkOutDoors on my Apple Watch Ultra then push onto Strava - had no issues at all, all the data matched. I then started use the Polar Verity to track my heart rate whilst using WorkOutDoors. Push the run onto and surprise, surprise, I have the same issue as yourself. Sometimes there is as much as 3mins knocked off my run on Strava. Makes zero sense.
Reached out to all three - WorkOutDoors, Polar, and Strava - and all three advised there is no error on their end. I tend to believe WorkOutDoors and Polar are correct and the issue is Strava as they’re incorrectly pulling the data through.
Tried multiple times to resolve the issue with Strava to no avail. And reading their response here is an absolute nonsense 😂 just pull the data through! It’s simple! So, so frustrating especially when paying nearly £70/year for Strava.
Poor effort Strava.
@barrymagee If the polar device measures heart rate only it has absolutely nothing to do with the distance. The problem is most probably that the WorkOutDoors app has to fallback using your phones inferior GPS reception in comparison to the very precise Apple Watch Ultra you used formerly. Everytime your phone fails to get the current location exactly it could lead to Strava assuming you made a pause and deduct that from the distance. You have of course a point if you demand that Strava should use the measurements that it got from the third party instead of recalculate everything, but in this regard Strava is set in their ways.
@Jan_Mantau I understand the Polar Verity doesn’t track GPS and it’s my Apple Watch Ultra and/or WorkOutDoors which tracks it.
However, I used the WorkOutDoors app using my Apple Watch Ultra and pushed the workout onto Strava with absolutely no issue. In fact, all the data was exactly the same. The issue only persisted since I started using the Polar Verity to track my heart rate whilst using WorkOutDoors on my Apple Watch Ultra.
To me, it makes no sense at all why using the Polar Verity heart monitor would affect Strava pulling the data through.
Okay, so you still use the same Apple Watch, you only changed the heart rate source from the watch to the Polar. In that case I don’t know why the distance in Strava would be affected. Maybe it’s coincidence, you could easily test that by using the watches heart rate the next time as you did before connecting the Polar sensor to the watch.
The upload to Strava from WorkOutDoors is all good. The trouble is when I introduce the Polar Verity to track my heart rate - Strava just can’t compute it and have my my actual Moving Time as Elapsed Time. It some how thinks I paused my activity for the minutes it cuts off my time (which I haven’t).
It’s a real frustration. I don’t understand why Strava struggles with it, not allow you edit the Moving/Elapsed Times without having to put every workout as a “Race”. Why Strava just doesn’t pull through the data from WorkOutDoors as it is, is baffling. There’s no need to reconfigure and recalculate and of the data.
