Has anyone besides Alberto Juanterano ever achieved sub 45 400M, Sub 1:44 800M double? Will anyone do so in near future?
Open 400m PBs of some "speed" based 800M runners
Rudisha - 45.15
I can't find a listed 400M best for Jouqim Cruz or Johnny Gray although Cruz was actually more of a 800/1500 guy than I realized.
