Ron Warhurst is the track coach at the University of
Michigan, and has coached the likes of Kevin Sullivan, Paul
McMullen, Tim Broe, among others, to fast times. He is
perhaps the best we have in the US right now for middle
distance training. What follows is from a coaching seminar
he gave a few years ago. With the recent thread(s) about
speedwork and mile training, I thought this might be of some
interest. I can also supply this by email as a word document
for anyone who asks for it.

Training For The Mile

Every coach has his own ideas which he incorporates into his
training program. Sharing ideas with other coaches,
attending clinics, readings and a coach's personal
experiences all help to formulate a coaching philosophy. As
training methods improve, a coach's training philosophy
changes. There are several methods used today, all of which
merit some discussion. A brief discussion of physiology may
help provide a basis for understanding the different
training methods used today. Physiologists have not
identified the exact mechanisms involved in determining the
working capacity of human beings, but much has been learned
about the adjustments that are made to the demands of the
activity. Three critical factors that seem to determine the
working capacity of the individual are:
1.Oxygen Requirement of the Task. This is simply the amount
of oxygen the body needs to perform a given task; the more
intense the activity the greater the oxygen demand.
2. Oxygen-Debt Tolerance. When the demand of a task exceeds
the capacity of the circulatory system to meet the oxygen
requirements of the tissue, a deficit exists. The level
of which the deficit can be built before one must cease
activity is called oxygen-debt tolerance.
3.Maximal Oxygen Intake. This is the amount of oxygen an
individual can take into his system during exercise. We
can assume that to increase the work capacity of the
individual, we have to be concerned with these factors. In
relation to running, if we reduce the oxygen requirements
of the run, increase the runner's oxygen-debt tolerance,
and increase the maximal oxygen intake, the performance of
the individual will be improved.
Aerobic and Anaerobic Exercise The controversy over whether
it is best to run long distances at a slow pace, or short
distances at a fast pace, centers around the concept of
aerobic and anaerobic exercise and the physiological
adaptations of the body. Aerobic means "with oxygen,"
anaerobic means "without oxygen."
Aerobic exercise takes place when there is an adequate
supply of oxygen carried within the circulatory system
during a given run. In other words, aerobic running occurs
when the oxygen requirement of the run does not exceed the
maximal oxygen intake of the runner.
Anaerobic exercise occurs when the circulatory system cannot
supply enough oxygen for a given runâ€"the oxygen
requirement of the run exceeds the maximal oxygen intake of
the runner, and a deficit occurs. This deficit is referred
to as the oxygen debt. During very fast running, oxygen
intake is inadequate to supply the oxygen required for
production of the energy demanded, so the energy for muscle
contraction is derived anaerobically through a complex
series of chemical reactions (KREB CYCLE). In these chemical
reactions, lactic acid is the end product of the anaerobic
metabolism. This build-up of lactic acid and the depletion
of the glycogen (the energy source which is stored in the
muscle tissue) results in the failure of the muscle to
contract any longer, and thus the runner slows down.
Endurance is the ability to withstand fatigue, or the
ability of the body to withstand fatigue, or the ability of
the body to withstand the stresses set up by prolonged
running. Endurance includes aerobic endurance, anaerobic
endurance, and muscular endurance. These types of endurance
are closely related within the unity of the human body. In
terms of running a given distance in the fastest possible
time, it would be most ineffective for the sprinter to
concentrate primarily on the development of aerobic
endurance or for the long distance runner to concentrate
primarily on the development of anaerobic endurance.
Aerobic Endurance, also referred to as stamina, is the
general ability to withstand fatigue of the entire body in
the presence of a sufficient supply of oxygen over a
prolonged period. It involves the ability to resist fatigue
under conditions where oxygen intake and oxygen requirement
for the run are kept at a steady and equal level. This is
sometimes referred to as cardiovascular endurance and circulo-
respiratory endurance.
By definition, aerobic running is running at a pace over a
given distance so that the running effort or pace does not
go beyond the capacity of the circulatory system to supply
enough oxygen for the effort involved in the run.
The more running that can be done at this pace (Lydiard
refers to this as steady-state running), the more efficient
the runner's respiratory and circulatory systems will
become. The stroke volume of the heart will be increased,
allowing a more rapid blood flow throughout the circulatory
system. With the increased blood flow, a greater volume of
oxygen and carbon dioxide can be exchanged in the lungs.
With increased activity more capillaries develop as well.
The increased efficiency of the respiratory and circulatory
systems will allow for more oxygen to be taken into the
body, thus raising the maximal oxygen intake of the runner.
An increased maximal oxygen intake is one of the factors
exercise physiologists have used in determining the running
ability (work capacity) of the individual. Also, the more
efficient the runner becomes, the lower the oxygen
requirement of the task becomes which is a second factor in
determining the ability of the runner.
Anaerobic endurance is endurance in the absence of oxygen.
It is the general ability to withstand fatigue of the entire
body when oxygen is in insufficient supply. This type of
endurance is especially important in middle-distance
running. Muscular endurance is local endurance which may be
either aerobic or anaerobic. The extent of the blood supply
in the muscles involved, oxygen transport at the tissue
level, muscle tissue viscosity, and muscle strength are
among the qualities upon which muscular endurance is
dependent.
By definition, anaerobic running is running at a pace over a
given distance so that the running effort goes beyond the
capacity of the circulatory system to supply oxygen for the
effort. This situation creates the critical situation of oxygen-
debt. Because of the complex chemical reactions that take
place, lactic acid is produced, and this lactic acid cannot
be easily removed by the cells within the muscles, so it is
passed into the circulatory system. The circulatory system
develops buffers to help neutralize the lactic acid, but
most of it is removed through the kidneys and liver. Much of
the lactic acid remains in the system and slows down muscle
contraction. This, along with a depletion of glycogen,
causes the runners to slow down. An increased oxygen supply
will allow the runner to go farther because the system can
supply more oxygen to the muscle cells, thus postponing the
onset of the oxygen-debt.
During anaerobic running the body becomes accustomed to the
stresses of performing in an anaerobic state. The more
efficient the runner becomes in handling the state of
anaerobic running, the higher his oxygen-debt tolerance will
become, and thus he will be able to sustain his effort at a
faster rate, and for a longer duration.
TRAINING METHODS
The most common method of training is the interval
system. It is a system of repeated efforts in which a
measured distance is run alternately with measured
recovery periods of low activity. The term "interval"
refers to the rest interval between the repeated efforts.
The control of the rest period is the most important
segment of the interval system.
The goal should be to reduce the rest period as much as
possible after the number of repetitions has been
established. This should be the primary goal in the early
stages of interval training. For example, instead of
running 10 X 440 @ 70 seconds with a 440 jog rest, run 10 X
440 @ 75 seconds with a 220 jog rest. From this point work
on reducing the time of the repeated effort to a level,
perhaps of 10 X 440 . 66 seconds with a 220 jog. A possible
format might be:
4. Establish number of repeated efforts to perform (10x440).
5. Reduce rest period between repeated efforts.
6. Reduce time of repeated efforts.
Overdistance Running involves training at distances greater
than those of actual competition, and may include continuous
runs of six to ten miles or more. The pace of such runs is
normally pre-determined and is usually slower than the
runner's racing pace. In pre-season training the pace should
not be as fast as it would be during the season, when the
pace for the over-distance runs should only be slightly
slower than the runner's racing pace. During the racing
season these runs should be timed.
Fartlek Running is kind of a combination of1 overdistance
and interval running. It is defined as "speed play,"
freetype running done over an in-j definite distance for an
indefinite time with some' segments of the run performed at
a faster pace than others, depending on the way the runner
feels during the run.
TRAINING PROGRAM
Research has shown that it is possible to raise an
individual's maximal oxygen intake by 9-13%. Since one
factor in determining a runner's work capacity is the
oxygen intake, this aspect should be dealt with first. The
question therefore, is how can the runner's oxygen intake
be increased? The crucial factor in determining the level
of oxygen intake is the limitations of the circulatory and
respiratory systems. The primary concern should be to
strengthen these systems, thus increasing the ability to
take in oxygen. To strengthen these systems you must
increase the heart-stroke volume capability of the heart,
thus increasing cardiac output. This will allow more blood
to flow through the system. An increase in capillarization
must take place as well. This too will allow a greater
volume of blood to flow through the system. Once the
systems become more efficient, a greater volume of oxygen
and carbon dioxide can be exchanged at the tissue level and
in the lungs. This increase in oxygen availability for the
muscles will help in postponing the onset of oxygen debt.
However, once the systems are loaded beyond their
capacities, oxygen debt becomes inevitable. When oxygen
debt occurs, the runner goes into a state of anaerobic
exercise, so the next aspect of training should be to train
the runner so that his body can withstand the stress during
this state of oxygen-debt, intensive interval training at
fast speeds can bring about these stress situations. During
the middle and late stages of the racing season this type
of training should be stressed.
Beginning Training Continuous slow running (7:00 pace or
faster)should be done during the summer months. This running
should be relaxing with little emphasis on running races.
This type of training is most effective in terms of
producing aerobic endurance. It is a superior method of
increasing the stroke volume of the heart, capillarization
of the local muscle groups, and generally increasing the
efficiency of the respiratory and circulatory systems. This
type of training is the first step in gradually adapting the
runner to tolerating the stress of running and the increased
ability to withstand fatigue. This summer running (on roads,
cross country courses, and golf courses) is the basis for
your fall program and the basis upon which later to apply
faster training. During the fall, continuous fast running
can take the place of the slow running thus increasing the
aerobic capacity and increasing the ability to handle the
stress encountered in running at faster speeds. During the
fall the training emphasis should be on developing strength,
stamina and the basic aerobic capacities. Interval training,
when used, should help develop the anaerobic capacity with
an attempt to reduce the rest interval between repetitions.
In early season the repeats should be run at about race pace
or slightly faster. Mid-season interval training should be
at race pace with the rest interval reduced. In late racing
season, speed-interval training should emphasize the quality
of the effort run, with more 'rest in between the timed
efforts. The number of timed runs can also be reduced.
This, hopefully, brings about the "sharpening effect" we
attempt to reach in the big meets. (See Fall Training)
Winter Training
A major problem a runner faces in Michigan during the winter
months is where to train. The answer is outside. A pair of
gloves, a wool hat, long underwear, and a hooded sweatshirt
is all a distance runner needs for the winter months. At
Michigan we go outside 5-6 days a week unless it is below
zero or the roads haven't been cleared of snow. I have seen
many runners train very hard and become very fit during the
fall. They have built their strength and endurance to a very
high level. .What many fail to realize is that they must
become more capable of handling the interval-oriented
training program for the half mile and mile. Improvement of
leg speed can be accomplished with 110's and 150's as well
as 55 yard in-out sprints during this period. These sprints
can be run on roads, in parking lots and on the outdoor
track if it s cleared of snow.
You might say the runners need a break from the pressure.
The pressure comes not so much from the training but the
anticipation of racing. From November 1st until February,
there are very few races a high school runner can perform
in. These three months allow a runner to continue ils
strength training with no pressure to race, popefully, this
will carry him over to the spring len the pressure races
become important.
If intervals are used as a basis for training during these
months, strength (endurance)-oriented intervals should be
used. Example: run repeat miles, 880's, and 440's (run at
slower than race pace with litye rest between repeats). The
speed-interval should be used in early spring. The 110's,
150's, and 55 yard in-out sprints should be enough "speed
work" during this period. (See Winter Training Insert)
Spring Training (March and April)
Maintaining strength and stamina (aerobic capacity) are
atill very important during the early spring. I would
recommend runs of 8-10 miles twice a week supplemented with
110's, 150's, and 55 yard in-out sprints.
The emphasis during this period should be placed on the
development of anaerobic running. Faster intervals can be
run, race pace and faster. As the weather improves
(hopefully) the speed- interval training should'be done,
possibly three times a week. You should only run fast
intervals two days in a row. *
Example: Monday interval Tuesday Interval Wednesday Distance
and pickups Thursday interval Friday Distance and pickups
Saturday race Sunday Distance
The distance day between hard intervals allows the runner to
recover from two successive days of fast interval training.
The speed interval sessions might consist of 440's, 330's,
220's, and 150's. Staircase sessions starting with an 880,
660, 440, 330, 220, 110's, might be used. During this period
the 110's should be run at top speed, only after a complete
warmup and stretching. Interval sessions with a maximum of
12-14 repeats are more than ample to bring about the desired
effects, if the fartlek and 110's-150's were maintained
throughout the winter training period. Determining how fast
the intervals should be run depends on several factors.
First, how fast has the athlete run a mile? How fast can he
run a 220? Was he on a winter training program? As the
performance of the runner improves, judgments on changing
the speed of the repeated efforts in the workouts can be
made. (See Spring Training Insert)
Weight Training
Every distance runner needs upper body weight work. We lift
weights two-three times a week during the fall and we
continue the weight training throughout the year. The winter
training period is an excellent time to concentrate on weight-
lifting. Use curls, bench presses and presses as well as
rowing. One or two sets of 8-10 reps would be sufficient.
The weight session should only last 10-15 minutes. If
weights are not available, push-ups and pull-ups are
excellent.
