Time to Recovery (TTR) represents the amount of time to recover from a high-intensity effort. Time to recover can also be associated with a recovery intensity. For example, TTR at rest (0 W) is shorter than TTR at 150 W, assuming Threshold Power is above 150 W. That is, you recover sooner at 0 W than you do at 150 W. Using a recovery power other than 0 W is useful to keep track of how long it will take to recover while still producing power, such as riding in a group behind the draft. Recovery power cannot be greater than or equal to Threshold Power.
TTR is a key feature in workout design using Target MPA.
