I’m sorry but this is untrue. I’m a 14 year old girl and i started of with an 81. That is pretty bad. I was being creamed pretty easily back then. Now I get 68’s and 69’s and I’m beat a lot. I live in VA and that isn’t excactly the ‘runners’ state if you ask me. I know girls that run 60’s and 59’s. I was untrained when I got an 81.
Same is true for the most talented girls. Raevyn Rogers ran 53 sec at age 12, and I still remember when some people here in the forum said it's a century talent and will threaten the doped record of Koch one time. Well, she only improved to 52s which she PR'ed last year (at age 21ish), she is primarily an 800m runner tho.
400m speed (same with 100+200m) is mostly genetically determined, by the ratio/amount of your fast-twitch muscle fibers. It's almost impossible for someone who is naturally slow to become much faster due to training. It's nothing like distance running, where huge improvements can happen with training.
I always say - if you are FAST (in sprints), you will know it long before you even start training. That's how much talent / natural ability matters!
