dude you know what he meant, im just sick of those pound em out mileage whores, you gotta be smart, you gotta be willing to say no to that urge.. its hard, i know in college i was surrounded by people trying to push 80 mpw but honest, they didnt do any better for it, they pretty much all ended up hurt or tired. I was alway fresh. you can debate all you want, but the proof has been clear pretty much universally between all levels of competition, less is in fact more, and doubling DOES help more than singling. you do doubles you are more fresh and you hit the same amount in miles, boom, you are in there. you are going to be running fresh feeling good on race day, and more consistent. if you get anywhere near 100 or over in college you just flat out wont be as successful as you could have been if you were at 70s or 60s... it is a progressive over loading process the body must go through, if you are still young, and only 4-5 years into it, 60s or 70s is perfect, MAYBE after running there for like 10 years, you can get up to 80s, then when you are in your 30s and it is marathon time, you can start with the 100s. basically all the literature I have read has lead me to the same conclusion.
