Polar M430 watch

Who didn’t get into this? Your training is finished, and you forgot to stop training on your lovely Polar watch. If you are not lucky, you will drive a long way home with a Polar monitor your “training” in a car. 
Looking for a beer in your kitchen you noticed this, stop a training session and sync it. Before checking your Olympic results you curse and call a friend for help. Of course, he doesn’t know how to solve this. 

But the solution can be quite simple. 
Leave your phone a little rest and switch on your computer. The solution isn’t available on the Flow app.
Open the web version of Polar Flow and click on your failed training session. Take a pencil and piece of paper and write down the time and distance to your training stop point. 
On the upper left side of the preview, you will find a “more” button/link. Click on it and you are almost there!

A new type of view has the “Duration” and “Time” fields EDITABLE. This is the key to our solution. 
Change wrong data with data from your training stop point and click on the “Save” button. 
This will shorten your training session appropriately. 

After you finish this procedure, go to the kitchen refrigerator and take a cold beer.
