Coach Jack Daniels passes away at 92
The world lost three of its greatest distance running coaches this year in a short span.
3-time Olympian and University of Oregon Coach Bill Dellinger. Adams State Coach Joe Vigil, and Olympian and Cortland College Coach Jack Daniels.
Besides being great coaches, all three were great men.
Here is the New York Times' great profile of Coach Daniels by Jere Longman.
I have in-depth interviews with Coach Daniels and Vigil in my book "Positive Splits."

Jack Daniels, Olympian and ‘World’s Best’ Running
Coach, Is Dead at 92
Tutoring Olympians, he created a simple workout formula that
was said to produce the best results with the least effort, earning accolades
across the running world.

Jack Daniels, a two-time Olympic medalist in the modern
pentathlon and an exercise physiologist who was once described by Runner’s
World magazine as “the world’s best running coach,” died on Sept. 12 at his
home in Cortland, N.Y. He was 92.
His death was confirmed by his wife, Nancy Daniels.
Over seven decades, Daniels, armed with a Ph.D. in the
subject, researched the physiology of running and coached Olympians and elite
college athletes, as well as recreational runners. Perhaps his greatest
contribution was to simplify and make accessible to coaches and runners of all
levels — from the high school history teacher who doubles as a track coach to
the world-class marathoner — the complicated science of human performance.
A runner or coach does not have to wade into the weeds
trying to understand the nuances of Daniels’s measure of running fitness, which
is based on the amount of oxygen consumption and goes by the acronym VDOT.
The only thing required is the numerical time it took to
finish an all-out race — say, a 5K. That time can be plugged into an online
calculator or compared with charts that Daniels and Jimmy Gilbert, a
mathematician, devised in the 1970s. Daniels published it in 1998 as “Daniels’ Running Formula.”
The formula predicts an individual’s time in races of
various distances, such as a 10-kilometer, a half-marathon and a marathon. It
also establishes optimum paces for training runs of varying levels of
intensity.
Daniels proposed individualized workouts for a runner to
obtain the best possible results with the least amount of effort. A runner
should not run too far or too fast, he suggested, and should avoid so-called
junk, or unnecessary, miles.
“Before Jack, nobody knew how fast or slow they should go in
training,” Amby Burfoot, the winner of the 1968 Boston Marathon and a
former executive editor of Runner’s World, said in an interview. It was Burfoot
who gave Daniels the best-coach appellation in the 1990s.
Critics said Daniels’s formula did not account sufficiently
for individual variation. But others disagreed; Mike Smith, the former head
coach at Northern Arizona University, who now trains Olympic-caliber runners,
described it as “shockingly accurate.”
The criticism hasn’t diminished the formula’s popularity. This year, the
VDOT online
calculator averaged more than a million computations a month from
users in more than 100 countries, said Brian Rosetti, who helped create the
calculator and a coaching
app with Daniels.

A coach and scientist of boundless curiosity, Daniels was
responsible for other innovations as well. In the early 1980s, he helped figure
out which running shoes were the fastest by determining that adding 100 grams
(about three and a half ounces) to the weight of a pair of racing shoes
increased the aerobic demand of running by about 1 percent — the equivalent of
an extra minute in completing the 26.2 miles of a marathon.
And when Joan
Benoit Samuelson, the winner of the first women’s Olympic marathon at the
1984 Summer Games in Los Angeles, had arthroscopic knee surgery 17 days before
the U.S. Olympic trials — a setback that could have kept her from qualifying —
Daniels came up with a workaround. At a Nike lab in Eugene, Ore., he rigged a
bicycle so she could sit beneath it and pedal with her hands and arms, keeping
her heart rate and her confidence elevated until she got back on her feet to
win the trials and an eventual gold medal.
During the track competition at the Olympics that year,
Daniels and Nancy Scardina, a former elite runner whom he married in 1985,
counted the strides of 50 Olympians in events from 800 meters to the marathon.
They calculated that roughly 180 steps per minute — with each foot strike
landing toward the runner’s center of gravity, creating a flowing or rolling
motion over the body — was optimal, because it minimized the time the body
spent in the air and reduced the shock of the landing force.
“He was one to think out of the box at all times,” Benoit
Samuelson said in an interview. “He was really ahead of his time.”
Jack Tupper Daniels was born on April 26, 1933, in Detroit,
one of five sons of Robert Daniels, who installed telephone switchboards on
military bases, and Louise (Giblet) Daniels, who ran the household. The family
moved to the San Francisco Bay Area when Jack was six weeks old.
He attended the University of Montana, earning a bachelor’s degree in physical education and mathematics in 1955. In college, he was a standout member of the rifle and swim teams, experiences that served him well when he joined the Army following graduation and won a silver medal in the modern pentathlon team competition at the 1956 Summer Olympics in Melbourne, Australia. At the 1960 Olympics in Rome, he won a bronze medal in the team event.

The pentathlon, meant to recreate a soldier’s challenges on
the battlefield, involves shooting, swimming, fencing, horseback riding and
running. But as Daniels wrote in his memoir, “Luck of the Draw” (2019), he received no expert
coaching in how to train for and run a race during his Olympic preparation. He
came to realize that it was counterproductive to run as fast as possible all
the time — that every workout must have a specific purpose, and that training
needed to be balanced with rest.
He went on to earn a master’s degree in physical education
and exercise physiology from the University of Oklahoma in 1965 and a Ph.D in
exercise physiology from the University of Wisconsin in 1969.
Preparing for the 1968 Olympics in high-altitude Mexico City, Daniels conducted tests on the effects of running in thin air while training in elevated areas like Alamosa, Colo.

Ahead of the 1968 Summer Olympics in Mexico City, held at an altitude of 7,300
feet, he and his colleagues conducted tests on the effects of running in thin
air. During training in high-altitude areas like Alamosa, Colo., Daniels would
sit on the hood of a car as it drove slowly around a track alongside runners,
like the star miler Jim Ryun, and would use meteorological balloons to collect
samples of air that they breathed into tubes.
In the summer of 1988, he wrote in his memoir, he helped a
relay team of Cortland runners set a national record by running roughly 3,000
miles across the country in 13 days and 18 hours.
The 10 men and five women were divided into three groups,
each group racing in four-hour shifts, said one of the runners, Judy Sparks
Arlington. Daniels, she explained, devised a strategy for runners to alternate
every 400 meters. This enabled them to run faster on each leg of the race than
if they had been running a mile or more.
“Absolutely, it was Jack’s brainchild how we did it,” Sparks
Arlington said.
In 2000, the N.C.A.A. named Daniels the top Division III
women’s cross-country coach of the 20th century.
In addition to his wife, a registered nurse, Daniels is
survived by their daughters, Audra and Sarah Daniels.
In the last week of his life, Daniels wrote a children’s
book to encourage families to walk and jog together.
“Jack’s goal was to get America fit, the world fit,” Nancy
Daniels said. “He wanted every kid to love to exercise.”

Mental Toughness for Runners
Without a doubt, the most common lament I’ve heard from runners in over

I know mental toughness when I see it: Alberto Salazar pulling away from Rudolpho Gomez in a cloud of dust after 24 miles, at sub-5 minute mile pace to win the 1982 New York Marathon. Lasse Viren getting knocked down, lying motionless, and then getting up to set a world record in the 1972 Olympic 10,000 meters. Bill Rodgers winning the 1975 Boston Marathon despite stopping to tie his shoe. These are just some examples that come quickly to mind. I’ve also seen mental toughness displayed from the high school runners I coach, sometimes when least expected: A freshman girl out-kicking senior runners in her first cross-country race, or a senior boy runner running negative splits and getting his best time in hurricane-like conditions. I’ve often wondered where the mental toughness comes from to rise above the ordinary.
Shakespeare may have framed it best when he said, “Be not afraid of greatness. Some are born great, some achieve greatness, and others have greatness thrust upon them.” Is the

Think about the races you have run where being mentally tough allowed you to rise above the pedestrian, above your perceived level of fitness to greater accomplishments. Maybe even to beat someone who you believed to be better. Wouldn’t it be great to know how to draw upon that same mental toughness at will? I decided to consult some of our all-time top runners for their views on mental toughness.
What exactly is mental toughness as it relates to running? According to Olympian and author Jeff Galloway: “The brain has two hemispheres that are separated and don’t interconnect. The

By preparing mentally for the challenges you expect, you will empower the right side of the brain to develop mental toughness. As we accumulate stress, the left-brain sends us a stream of messages telling us to “slow down,” “stop and you’ll feel better,” “this isn’t your day,” and even “why are you doing this?”
What is mental toughness?
According to 1983 Boston marathon winner


Bill Rodgers thinks the term “mental toughness” is “a description of how well an athlete prepares for the physical and mental challenges of their sport. I like the great Tanzanian marathoner Juma Ikangaa’s comment, ‘The will to win is nothing without the will to prepare.’” Lynn Jennings has said, “Mental will is a muscle that needs exercise, like the

First, create a competitive advantage through your training. Besides the physiological improvement that comes through investing more time in training, you receive a psychological boost if you do a workout that you believe no one else is doing. Hill workouts, negative-split workouts, and short fast repeats at the end of a long run are some of the ways runners look for a competitive advantage.
Galloway believes that incorporating mile repeats and long slow runs of 30 miles in his training enabled him to beat more talented runners and make the Olympic team. Bill Rodgers: “Most of my daily runs (two a day) were at a moderate pace (6-7 minute miles for me), but I always ran by how I felt. If I felt decent I would run harder for several miles at a time. This was true for 5 to 25 mile runs. I was trying to teach my body to ‘float,’ that is run as effortlessly as possible in some training runs.”
Finally, train with other runners. Jumbo Elliott, long-time Villanova coach, was fond of saying, “Runners make runners.” The synergy of proper training with other runners in a supportive (and not overly competitive) environment can take your training to another level while enabling you to run closer to your potential.
Gerry Lindgren, considered by many to be America’s best high school runner ever, ran a 13:44 5000 meters and an 8:40 two mile in high school and beat two World Class Russian runners,

“I used to do a lot of exercises to increase mental toughness. It was a game I used to play. Every time I went around a curve in training I went to the outside in training runs so I had to run further. I always had to take the hardest longest way to build mental toughness. I chased bikes. I did sprints at certain places in my training runs no matter how I felt. Every time I came to that place I had to sprint! It slowly built up my mental toughness.”
Salazar trained by running hard ¾-mile intervals at the start, middle, and end of his runs. Alberto recalls running against Rudolpho Gomez: “I actually had two races against him in New York—1980 and 1982. The 1982 race was of course the very close race. I remember being scared of his kick, so I tried to soften him up with surges over the last two miles. They worked as I only beat him by a few seconds, and if I’d waited, it might have turned out differently.”

Second, train your mind. Frank Shorter says, “I think simulating racing while interval training is a good way to gain mental toughness. Imagine yourself in the race situation. Then, when you are actually in it, it will seem ‘familiar.’”
I tell the Gloucester Catholic boys and girls cross-country teams I coach that mental toughness is like a muscle that grows stronger through use. Passing someone when you are tired, surging, or starting your kick at a predetermined place—all of these things build mental toughness and make you that much tougher for the next race.
Jeff Galloway recommends fartlek training as a way to enhance mental toughness. Because there are no artificial barriers on time, distance, etc, you reduce the negative messages from the left-brain when things get tough: “Fartlek develops a sense of focus and resource coordination not found in other forms of training. You’ll still get those ‘pings’ from the left side but they won’t bother you as much. Fartlek desensitizes you to the discomfort and uncertainty of pushing and pacing beyond your current limits.”
Bill Rodgers agrees: “I recall using a technique while racing of visualizing an Olympic gold medallist at 10K, who was a terrific competitor; I would emulate his running form to steady myself mentally over the final miles of a race. I think training and racing a lot makes you experienced, i.e. tough as a competitor.”

Salazar says “Back in the ’70s and ’80s, it was felt that one’s mental toughness, resilience, and ability to focus were God given and could not be enhanced. Now, common sense tells us that even the naturally toughest competitors can become more relaxed and more focused through the use of mental and psychological training.”
Relaxation, visualization training, and hypnotherapy are all common psychological training tools. Steve Prefontaine once said: "Most people run a race to see who is fastest. I run a race to see who has the most guts."
Third, make sure you are really giving 100% effort. Larry James, the Olympic 400 meter gold (4x 400 relay, world record) and silver medalist from Villanova and a long-time coach and Athletic Director at Stockton College believes: “You can only give 100%. Whenever I hear

If you are able to give close to 100% effort more often than your competition, you will appear mentally tougher than your competitors. Olympian Paavo Nurmi once said: “Mind is everything—muscles pieces of rubber. All that I am, I am because of my mind.”Fourth, break the race or workout into segments to make it more manageable. For example, author and former AAU champion Tom Osler recommends breaking a race such as a marathon into thirds: “The first third is run easy; the second third you start to get competitive and run at a relaxed pace fast enough to catch runners in front of you. Only the last third is raced at maximum effort.” Osler was also one of the proponents of inserting walking breaks in long runs to make them more manageable.
Our high school runners are taught to start their 5K kick with about a half-mile to go, and to run against the clock. By picking a point in your race in advance where you know you will go hard you are able to embrace discomfort for a manageable amount of time and also to use the element of surprise to appear mentally tough to your competitors.
Also, by not playing it safe emotionally, you will start to perceive yourself as a tough runner. By breaking the race into segments and by concentrating on running as hard as possible in that segment you will increase your mental toughness and test the mental toughness of competitors. Gerry Lindgren would often sprint the first quarter-mile after the four-mile mark of the race

Bill Rodgers: “My friend Andy Palmer used the motto “The Mind is the Athlete” as part of the philosophy he passed on to his athletes. I see talent as physical and mental. I think everyone has the innate ability to be mentally tough; what counts is whether one has the desire to explore that to the best of their individual physical abilities.”
Fifth, use your self-discipline to know when to and when not to push yourself. Knowing that you alone decide when to push and when to hold back can relax you and enable you to ration your energy for use at the right time.
Tom Osler says “the urge to push in extreme weather conditions in pursuit of developing mental toughness is counter-productive.” Osler continues: “You can’t beat Mother Nature. You will run much better, and be able to push harder in a race if you train at the coolest part of the day for example.” Coach and author Roy Benson adds: “Mentally tough runners have the discipline to

Where the mind goes, the body will follow.
It turns out the inscription on our family crest translates to a useful slogan for anyone wishing to call on their own mental toughness: “Espere Mieux”--could be translated to “expect or wait for the best.” If you wait for the right moment and expect the best in each running situation that requires mental toughness, you will be much more prepared when you have your own “cloud of dust” moment. You will emerge from the other side victorious because you expected to do well based on your preparation. After all, your mind has already seen you do it before and expects nothing less.
