I’m using Train Now for some ad hoc training. The workouts are annotated A - Achievable, P - Productive, S - Stretch. I can’t see a definition but am assuming that Stretch is a possible fail level of intensity but A vs P? The workout recommended today is an Achievable with Productives available for not TR’s recommendation. What am I getting with As vs Ps?
Thanks folks and sorry if this has been answered elsewhere but I couldn’t find it.
