Time to Recovery

Also referred to by the acronym TTR, this 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 watts) is shorter than TTR at 150 watts, assuming Threshold Power is above 150 watts.  That is, you recover sooner at 0 watts than you do at 150 watts.  Using a recovery power other than 0 watts 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.
