Firstbeat features (4)
Forerunner 920XT packs a fleet of high-end training features into a sleek watch that is wet suit-friendly and about 15 percent lighter than its predecessor, the Forerunner 910XT. It boasts a high-resolution color display; flexible, hinged bands and a watch mode, so you can wear it all day. The activity tracking5 feature measures your steps, sleep and calories burned all day, giving you a more complete picture of your daily activity.
When used with a heart rate monitor, Forerunner 920XT offers additional features that can dial in your recovery status as well as your racing potential. First is a recovery check, which is a real-time indication of your recovery state within the first several minutes of an aerobic activity. After the activity, the 920XT provides a recovery time indicating how long before you should attempt another hard effort. The 920XT can also estimate your VO2 max for running when used with HRM-Run™ and for cycling when used with a heart rate monitor and power meter. Based on that data, it can predict your running race times for several distances.
