Take a look at the October issue of Track&Field News.
There's a picture of Sureyya Ayhan, and another picture of Gabriella Szabo and Suzy Favor.
Such a striking difference in the difference in the strength and development of these runners.
Look at the muscles in their legs.
Ayhan looks in supreme fitness, as does Szabo.
Obviously these runners work very hard to get where they are.
Then look at Suzy.
She looks like she's been sitting in a hot tub for three years.
She is obviously a very fast and talented runner, but not nearly the fitness of the others.
Is this just my impression or do some of the rest of you see this too.
