Your spikes, which were really quite long then, would catch the material of the track and your shoe would get heavier. I was simply filing them down and rubbing some graphite on the spikes, so that I thought I would run more effectively.

My athleticism was really the core to social acceptance, because in those days the overwhelming number of students came from more of a public school background than I did.

Just because they say it's impossible doesn't mean you can't do it.

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

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.

I trained for less than three-quarters of an hour, maybe five days a week - I didn't have time to do more. But it was all about quality, not quantity - so I didn't waste time jogging, ever.

It's a question of spreading the available energy, aerobic and anaerobic, evenly over four minutes. If you run one part too fast, you pay a price. If you run another part more slowly your overall time is slower.
