Anna Hall fun fact: she says she does zero "just mileage" running, and her weekly interval volume totals up to 2-3mpw.
This got her to 2:03 at the end of a hep.
Granted, she's out there all day lifting throwing and jumping too so "Only 3 mpw for a girl to run 2:03 in the 800" is a disengenous statement, but another good example of mileage not being all that important for a solid 800.
