Thanks. I believe it is. However I couldn't try it as the run was deleted from my watch because I deleted it from the Polar app on my phone. I assumed that this would just delete it from the app and it would stay on the watch (literally no idea why the watch data was deleted). Strange sequence of events, but I will try it soon just for peace of mind.I’m not familiar with Polar, but with Garmin when you plug the watch in to a computer you can access the activity files, which can then be manually uploaded. Perhaps that is possible?
