Athletics is a luxury.

It seems quite impossible to walk in America.

You get very tired, and there was a certain amount of pain and you slow up. Your legs are so tired that you are in fact slowing. If you don't keep running, keep your blood circulating, the muscles stop pumping the blood back and you get dizzy.

Mothers, unless they were very poor, didn't work. Both of my parents had to leave education. My mother had to work in a cotton mill until 18 or 19, when she took some training in domestic science.

Every time I ran the mile I was aware of my own weakness, there was some opponent who could give me a hell of a fight, so I never went into a race with a sense of invincibility. I always had that feeling of fragility and nerves which made me run faster.

Whether we athletes liked it or not, the 4-minute mile had become rather like an Everest: a challenge to the human spirit, it was a barrier that seemed to defy all attempts to break it, an irksome reminder that men's striving might be in vain.

I couldn't touch my toes with straight legs, but I could break 4 minutes for the mile.
