I haven't gotten a copy yet but i find that part of humanity interesting in that we seem to continually pursue the need to find/design the perfect physiological specimen for athletic games. There are so many factors including genetics, environment, training plan and motivation that really narrows down the selection. How many slip through the cracks? How many in the last twenty or thirty years or more decided to try to gain unfair and unnatural advantages over the other competitors? Remember when pro football players (linemen) had big guts and not stacked like brick shithouses like today's missles trying to take each other out? A lot certainly has changed since the 60's.
In a time where there was less science and technology involved, there seemed to be a greater amount of diversity in physiology. In other words, they didn't all look like each other like today's top elites. Example: 1984 Olympic Marathon. DeCastella, Australia, world record holder (huge legs) was one of, if not, the favorite going in but finished 5th. Juma Ikanga, Tanzania (typical high altitude African) Takeshi So, twin brother & Toshihiko Seko all trained under the Japanese system, Joseph Nzau, Kenya Carlos Lopez, Portugal, 10k world record holder, world cross country champion, eventual winner, Charlie Spedding, England & Bronze medalist and John Tracey, Ireland & Silver medalist. Oh yeah, Alberto Salazar 15th.
So many different training environments, genetic backgrounds, corners of the world, not necessarily all training together in camps etc... It was just fun waiting to see who was going to survive the conditions, pace, tactics etc... and get to the line first. Probably my favorite marathon race of all time. It really was anybodies race going in. Interestingly, the guys that survived the heat the best to medal were from relatively cooler countries. I remember Treacy and Spedding both having to be carried around afterwards and during the awards ceremony and closing ceremonies. Great times.
