Shady, or terrible coaching at KSU?
Galvan competed collegiate for Kansas State (career ended in 2015). In college, she had PBs of 4:29/16:37 but now she's run 4:10/15:27.
Some people actually get faster after college, some people actually get a lot faster. They do this despite the Letsrun consensus that while you may be slow in high school, and then fast in college, you may not be slow in college and then fast in “real life”.
