Polar rolled out another update for the M400 and V800 watches today, adding support for speed and pace zones. These metrics work exactly as heart rate zones, allowing you to stick in a specific range where you want to be. It’s just the speed or pace you bike and run. You can set the boundaries of your zones in the flow sport profiles and create training targets based on these zones. During your session you will receive information on where you are and where you should be.
Also, there have been some small improvements for the V800 on swimming again after November’s bigger update. The detection of turns (flip or not) has been improved and the overall algorithm has a better support for the faster swimmers amongst us.
