In last week's episode, Frank Shorter talked about following your instincts, knowing when to press and when to rest in training. BUT... that is easier said than done. It's really hard in practice and generally takes a lot of experience to get the balance right. Even at 20 years of running, however, I still make those mistakes.  In this episode, I give you cues to use within a training season and within a workout that tell you when to back off and when to go for it. How do you know when to back off in training? How do you know when not to do the full number of reps? Those are the critical questions that I try to answer for you in this episode.
