”RW: When you were doing marathons, did you follow a fairly strict training regimen, or did you just kind of make up your own?
JE: It was strict in the sense that I always tried to run at least an hour a day. I never missed more than one day a week, usually none. As I got closer to the marathon date, I would try to do longer training runs, at least 2 or 3-hour runs.

RW: Those long runs are the key. So how were the marathons themselves?
JE: I ran too fast in the beginning, almost every time.

RW: Sounds familiar.
JE: And then when I'd get to 17 or 18 miles, I would slow down. But like most people, when I got to about 18, 19, 20 miles, right in that range, it was a remarkable difference.

RW: The Wall.
JE: Yeah. The Wall really happens.

RW: So how do you get through that?
JE: It's all in your head. Finishing a marathon's in your head.
