I'm sorry for those who have never had the opportunity to meet Jack Daniels, or to understand his physiology brilliance, training insights, and influence on world class distance runners. Daniels is basically the foundation for all modern training approaches.
Furthermore, those who know Jack best would be the first to agree with the above statement. Just a few notes:
# in 1968 Daniels helped American distance Olympians prepare themselves for the basically impossible task of competing at Mexico City. He was the one who best understood the altitude challenges and what could be done to get ready
# in the late 1970s and beyond, he worked for Nike, testing many of the company's top runners of that era, and advising them on their physiology results and their best individual training programs. He was an "official coach" to few of these athletes, but ask any of them if they learned anything from Jack, and I can guarantee you the answer will be "Yes. Lots."
# in 1984, a desperate Joan Benoit decided she had no choice but to undergo knee surgery two weeks before the first U.S. Women's Olympic Marathon Trials. When she came out of surgery, she couldn't put weight on her leg. So Jack suspended a bicycle upside down over a table, and told Joan to arm-pump the pedals for exercise. It's not likely that anyone else could have conceived this ingenious strategy. And you know where Joan went from there.
# Jack also coached Ken Martin (2:09:38, NYC, 1989), Magda Boulet, and too many other greats to be mentioned here.
# He's funny, low key, disparaging towards none, and has spoken at hundreds of national and international coaching clinics, where he has been widely appreciated. He has always freely shared his insights and knowledge.
# His core training philosophy--"Do the least amount of work you can to achieve your goals"--has stood the test of time.
# Jack will turn 90 in mid 2023. I wish we could turn the clock backwards, and have him around for another 90 years.
