Hmmm.....
My daughter is a freshman runner on her highschool cross country team. She has some talent and finished her first two races as the second runner on her team in both races.
A lot of the upperclassmen are telling her to enjoy it while it lasts because they all got slower as they got older and it will happen to her too. Is this just the blabbering of jealous upperclassmen getting beat by a freshman, or do girls generally get slower as they mature?
