You have to run 75 to 100 miles a week if you expect to break the four-minute mile.

Now I say that if you run more than 15 miles a week, it's for something other than aerobic fitness. Once you pass 15 miles, you do not see much further improvement.

Over the years, I've covered 22,000 miles.

You need a 1000-nautical mile runway to do it and we only have 628 nautical miles.

We sometimes run one mile hard and one mile easy, and we do this for maybe four or five miles.

You don't run 26 miles at five minutes a mile on good looks and a secret recipe.
