I'm lucky enough to have a 1962 edition of the book 'Run to the top' by Arthur Lydiard, and a 1960 edition 'How to become a Champion' by Percy Wells Cerutty. Yes the pages do smell 50 years old but are filled with gold

Work does things.
But work simple never did great things or every labourer would become a rich man. Every one who trained sincerely and long – a champion.
We know they do not.
It is the quality of the work that is important.
Work does things.
Intelligent work does things better.
To stop when it hurts is to stop when it works.
If you are a stopper when it hurts, you can rest assured that you are not destined to go very far.
Try tiddlywinks instead.
I recall two lads. One an ugly duckling, weakly and gangling – he started at twenty years of age in the lower 10 percent of the athletes in this country. He was a ‘joke’ in his club, rated so low as to not even making club teams. He came to see me for lessons. He improved his four mile time by two minutes in one season. Awkward and un-coordinated as any athlete in my experience, he was endowed with such a simplicity of outlook, such a capacity for punishment and effort, that my heart has bled inwardly for this man. He went on to become the champion of his club in every event from the 880 to ten miles, and from memory I should include the 440.
No other athlete is ranked higher in my esteem or affection. But the world has never heard of him. His name was Les Fricker.
In our camp, Fricker is a standard – to strive like Fricker is to be ranked with the highest; as a trier and punisher he has no superior. A simple name, unhonoured, and unsung elsewhere, he rates with the highest at Portsea.
It is the ‘overcoming’, not the ‘success of’, that is important.
