13:48 guy here and lived with a guy who ran sub 4:05 countless times but never cracked 4. both of us were liberal arts students so school was never too challenging except around midterms and finals. we drank hard probably once every two weeks or three weeks. occasionally had a few toking sessions but that was mostly during summer or in between seasons. there were some random girls of varying degrees of attractiveness. but the best nights were those when a bunch of teammates did random things like wrestling, chugging hot sauce, drawing phallic symbols with a sharpie on whoever passed out first, and other stupid stuff i miss so much.
looking back i realize focus in running is so individual. some will thrive off of a spartan lifestyle while others need a girl, drink, party or whatever every so often to calm their nerves before they go berserk.
