That’s 2 coaching examples but Virgin, Fernandez and Grijalva all came from high schools with zero distance running traditions.
There have been countless 800m records set by someone that led the entire race. You’ve never seen a race where someone tried to keep up with a slightly faster runner, got dropped and then got passed passed by others coming down the home stretch? It happened to Wolhuter at the 1976 Olympics and maybe if he had hung back, he could have won the Silver. Stupid.
