Runners like to train 100 miles per week because it's a round number. But I think 88 is a lot rounder.
Grizzly bears eat people without the benefit of music.
Without ice cream there would be darkness and chaos.
Avoid any diet that discourages the use of hot fudge.
Train at the same pace day after day, week after week, year after year, and that's the kind of running the body adapts to. But break out of that comfort zone with a little speedwork now and then, and the body will learn to deal with the new demands.
Prior to the 1976 Olympics, I was a 5,000m runner.
