Kevin Helliker, WSJ, Sept 9, 2014, says more and more athletes may concentrate on a faster "mile" rather than those 26-mile slogs. Or those 100-mile marathons.
Less is more (impressive)?
Recently a guy ran the 3 minute 58 second mile.This gained him respect at his office, which was full of jocks.
A study (of course) showed that adults who ran less than an hour a week over a 15-yr period lived longer than those who ran three hours.
Even little kids can run a mile, although some PE teachers have to be convinced.
And--when you run a marathon, one runner said, they ask you what your mile pace is anyhow.
So why take all day to prove something?
