As girls/women go through their maturation phase - typically sophomore/junior years - their times tend to plateau or decline
assuming attention to other details - training, diet, etc - once through this phase can improvements continue to be expected - or is this typically peak performance
trying to keep several girls motivated when they aren't dropping times like they think they should when their bodies are going through these maturation changes
have several girls who have the talent to run in college but are frustrated because they think they have peaked in high school
