It is nothing more than a reflection of the talent pool in the sport now vs. then. In another 10 years we may well be back to sucking. It has nothing to do with mileage.
I beg to deffer. The talent pool, if anything, is higher now. I read in a book by Matt Fitzgerald, that there are 23 gene mutations (one for each chromosome) that favor success in distance running ability(these specific genes do not determine recovery rate, injury proneness, etc just running ability and potential).
1 in 10,000 people have all 23 gene mutations. If you have all 23 you're a world class talent. There are more factors to success than just raw talent; such as training environment, coaching, work ethic, additional gene mutations that favor faster recovery and higher responsiveness to training.
But if 1 in 10,000 people have the genes for world class running, then as the population goes up the talent pool goes up. With 313.9 million people in the USA, that means 31,390 have world class running genes. About 30% of Americans are between the ages of 19-39(ideal age range for endurance sports). So about 9400 people have the world class running genes and the appropriate age range to be competitive, or about 4700 people per gender. If you want to limit it to people 19-29, then cut the numbers in half.
Now the question, is if we have the potential for such masses, why don't we have 2000+ elite distance runners per gender?
I think its cultural. Maybe the next Jim Ryun eats chips and plays video games all day and weighs 250 pounds by the time he starts high school. We have a lot of potential talent fall through the cracks. As a result, we have many people with imperfect genes running as elites. If you have say 20-22 of the 23 gene mutations, that's probably enough to get a shoe sponsor if you're in the right environment, work hard, well coached, and a little lucky. But without the perfect genes, you won't be competitive for gold medals, just the way it is.
In Kenya, they have the masses because talent is identified better. Kids without perfect genes still train very hard and are in a good athletic/running environment and reach all of their potential which can still get them quite good. This is why Kenya is above and beyond the most deep country in running talent. Just look at how many sub 210 marathoners they have any given year vs the USA. It's a world of difference. We have a larger population, we have a larger talent pool, but our environment and culture and inability to spot and prosper talent holds us back.
