From the 2005 thread, quoting Seb Coe himself directly, Martin-x wrote the following exchange:
"Coe was asked by a Finnish reporter if he was still active and fit (which, if you look at him, is self-evident: he's quite thin and looks much younger than his 49 years).
He said: "Yes, I run about 30 miles a week or so and lift weights a couple of times a week."
I asked: "How does that compare to when you were racing?"
He said (laughing) "It's quite different. I was doing about 100 miles a week in twice daily sessions back then."
I said: "As much as that?"
He said: "Well, not every week, but during the bread and butter months, I would get up to 100 miles a week. During track season, it would be much lower, of course, but I would say the average was about 70 miles a week."
Well -- that's it. From the horse's mouth, as it were, to the Let's Run board. Seb ran mileage. Lots of it.
I was wrong.
