Polar has introduced their latest fitness tracking wearable, the M400. The $200 GPS device is jam-packed with standard fitness tracking features like speed and heart rate, but also adds in more runner-centric items like a run-time estimator, return to start function, and weekly training.
Polar says the M400 will stay up for 24 days as just a watch/activity tracker, or 9 hours as a GPS device. You can connect to the Polar Flow app as well, checking out your data in more detail as well as seeing the routes of other users.
The M400 will be available in black or white later this year.
