We saw a great drama played out in the late 60's to mid 70's men's 
track. Jim Ryun  - trained to what would have been the "Tom Ivers 
protocol" vs. Kip Keno of Kenya. Ryun was one of the first 
"scientifically trained" distance runners. All other coaches (including 
mine)  minimics his coach. Ryun was the first high school runner to 
break the 4 minute mile. He held the record for the high school mile 
until recently. The use of intervals to build the use of lactic acid as 
a fule, the use of training methods to build the muscle substrate for 
distance at speed, etc.

Kip Keno, the Kenya who ran for miles and miles on the high plateau of 
Kenya - no fancy training. The outcome of the races, Ryun no gold metals 
- Keno several in everything from the 1500 meter, 1500 meter 
steaplechase, etc. . His son following in his footsteps winning at least 
one Boston marathon. Not that Ryun wasn't a great runner - but 
somethimes it's just in the genes.
