The Xert Time-To-Exhaustion, Time-To-Recovery Field is one of the most powerful, yet least-understood or used Fields in the Xert Ecosystem. But when you use it correctly, it can be one of the most powerful tools on your Garmin head unit.

What Is the "Time-To-Exhaustion" Xert Field?

The Xert "Time-To-Exhaustion" Field (TTE) is a little-understood field that performs a couple of functions. It can be found in the Garmin Connect App Store. Primarily, enter a known wattage in the "TTE" setup, and another known wattage in the "Time-To-Recovery" Field (TTR). Then install the Field on your Garmin Profile. When the phone syncs with the head unit, the field will populate two times. The "TTE" time will show how many minutes a seconds a cyclist has until their MPA (and High Intensity Energy - HIE) is exhausted, and the "TTR" will show how many minutes at a certain wattage are required for the athlete to recover. Alternatively, there's another setting. You can enter a known MPA as a "Floor", and another known MPA as a "Ceiling", Then, when you ride at ANY intensity, it will count down the time to reach that MPA, and then count down the time required to hit that MPA Ceiling for recovery. This is a GREAT TOOL for a lot of reasons!
