Rog, I agree with you on most of your post.
I don't want to take anything away from Rodgers, Shorter, and Salazar but they competed in a much differnt era. When Rodgers made his big breakthrough in 75 he was suddenly one of the top marathoners in the world and a real contender for an Olympic Gold Medal. Shorter won gold in 72 by breaking away 10 miles into the race and winning in 2:12.
Today a 2:09 marathon is nobody special on the world scene.
The many great runners in the 70's were training hard and pulling out all the stops to be the best they could be. Those who are competing today are doing the same.
You don't think Culpeppar and Dan Browne are training hard?
One thing that is different is the HUGE psychological factor that being one good race away from number one in the world, the adrenaline, optimism, boost to the ego, rush, and motivation. Jorge Torres and Adam Goucher came out of college pretty much at the same fitness level as Salazar, Pre, Virgin , and others. But while those guys were racing for wins in Europe today a 13:15 guy makes the final in the Championship meets and finishes dead last.
Now I agree that there's no use in complaining and the only thing you can do is keep training hard but it is a barrier to overcome, this huge gap from national class to world class. This gap wasn't as big before the 90's and more people were encouraged to keep going in this sport.
So yeah, we had 191 people once under 2:20 aand I would bet every one of them had goals of winning Boston, making the Olympics, and being the next Bill Rodgers and a lot of people were running 100 plus miles a week in this country.
The World Record today is 2:04. We may never see another American win Boston. And fewer people are holding off careers to concentrate on marathons.
Maybe were just pussies today as was mentioned earlier. But things are not exactly the same now as then and being a pussy as opposed to running clearly for intrinsic reasons is the easier choice.
One person who has the talent and heart to actually gain real glory, like Shorter and Rodgers, is all it would take to turn the tide.
