May is a very early time in the year and the weather is usually bad. You cannot run a fast mile race if there is a strong wind, because it makes your running uneven.

I was always a great bundle of energy. As a child, instead of walking, I would run. And so running, which is a pain to a lot of people, was always a pleasure to me because it was so easy.

The man who can drive himself further once the effort gets painful is the man who will win.

The man who goes on, even when it's the hardest to be the winner.

When I was about to break a world record and become well known, my mother used to say that for her the important thing was for me to become a doctor - a career which had not been possible in her generation and in her society. Sport was something to be set aside.

I lived on the top of one hill and the school was at the top of another hill. Nobody ever went to school by car - we didn't have any cars during the war. So that to and from school was itself a training.

The human spirit is indomitable. No one can ever say you must not run faster than this or jump higher than that. There will never be a time when the human spirit will not be able to better existing records.
