Don't allow people to upload the same activity twice from different devices

[rrajao]

I personally record my activities on my phone and also on my cheap GPS device as a backup, which I manually upload through the website in case the Strava app crashes.

Many people I know also record on their phone and another device, such as a Garmin or Apple Watch.

Problem is, most of these devices automatically upload the activity to Strava once it's finished, and when the person also finishes the activity in the Strava app, it creates a Group activity which double counts the activity.

Sometimes this is unintentional, but sometimes it's blatant cheating.

Hey @rrajao,
Thank you for submitting your idea.
We do have a feature in place already that detects duplicate activity uploads. However, we are always looking to improve our features.

I recommend heading to our Features Chat to share your feedback about detecting Duplicate Uploads.
Again, Thank You so much for your contribution!

Hi, I have duplicate Strava activities because of following fact:
1. my new e-bike Specialized automatically uploads to Strava: GPS data, climbing, speed, cadence, power.
2. my iWatch automatically uploads to Strava: GPS data, climbing, speed, est. power and HEART RATE.
As there is no possibility to synchronize heart rate monitor in iWatch with Specialized eBike, I have 2 separate records in Strava, just because Heart Rate is not recorded by e-bike.
I would welcome if these 2 sets of data from one training can be combined into one record (activity), or just import Heart rate date to e-bike activity.
Thanks a lot for hints and/or for consideration for future Strava updates.
