Hello Mr. Renato Canova,
I'm reading your posts for long time now and it's very usful, interesting and full with high quality of knowledge and material for me and for many many others.
I was wondering what is the definition you give for an athlete with great potential/natural talent in distance running.
Is it related with his basic speed/physique/technique or a combination of all?
To be more specific, I would like to perform a test that will give an estimation regarding one's ability to perform well on world class level saying running 2:07 marathon with proper aerobic buildup over the course of 10 years or more and then a specific preperation.
Thanks,
Oren
