Not really asking about equivalency tables, because I feel like high schoolers tend to perform better in shorter distances relative to longer ones when it comes to those. Sure a 4:30 is equivalent to a 9:38 but I'd be quite a bit more impressed by a 9:38 guy in HS than a 4:30 guy.
I'm thinking it would be "everyone ran a 9:48 2 mile in high school".
Thoughts? What about the 800? Everyone ran a 2:03 800 in high school?
