Counting the Steps...
I'll tell you mine if you tell me yours
Cadence, that is. Running cadence. Do you know
yours? Should you?
As amazing as it sounds, there is a common characteristic
found in the population of elite distance runners
that is apparently unrelated to the distance of
the event. From 800 meters to 26.2 miles, the
front of the pack has a high cadence, and they're
leaving us behind! Here's why and what you can
do to work on yours.
Running cadence is the measure of how many foot
strikes either the right or left foot makes in
one minute, and it's one of two factors involved
in your overall speed. There are only two ways
to get faster on the run: take longer steps and/or
take more of them. Interestingly enough, however,
observational research has shown that a runner's
cadence is the least variable of these and most
elite runners maintain a cadence of 85-95 regardless
of pace or distance of the event. What happens
is that runners adjust stride length to gander
speed, and the same quick turnover with a slightly
longer stride results in a faster race.
Does that mean we should all work on leaping
through the air like Baryshnikov in order to increase
our stride length? Actually, no. One of the most
common mistakes novice runners make is over-striding,
which is landing the foot fall too far in front
of their center of gravity, actually reducing
momentum and increasing chance of injury. The
stride adjustments made for the sake of speed
seem to be automatic and not the result of deliberate
over-reaching of the foot fall. It appears to
be one of those things our bodies just "know",
and the best way to improve stride length is to
increase muscle strength in the legs (via hill
repeats and resistance training, for example).
What we should do, though, is work on maximizing
the efficiency of our cadence, so that when we
do unconsciously adjust the stride length for
speed, we do so at an optimal turnover rate.
As mentioned earlier, there is a magic number
for cadence, and it appears across the elite distance
running population, regardless of distance, age,
gender, or breakfast cereal. On a flat course,
85-95 is common, with the ideal slowing to 60-65
on uphills and increasing to 100+ on downhills.
This cadence is high and necessarily implies fairly
short strides, minimizing time and the air and
reducing the force of impact between the foot
and the ground upon contact. Stride rate does
not change easily, but if you can train your body
to be comfortable at a faster cadence, you will
be able to sustain it in all of your runs, maximizing
your performance.
In order to determine your own running cadence,
do this quick assessment. On a normal training
run, time yourself for 1 minute and count the
number of times your right (or left) foot hits
the ground. Repeat this 3 or 4 times to find an
average. How close are you to 85-95? If you are
below 85, you are possibly over-striding and should
to work on increasing your leg turnover and shortening
your stride. If you're much over 95, you might
want to consider training with the Olympic team.
A great drill to incorporate into your regular
training is to run strides. Just as with swimming,
you can use drills to improve your running technique,
paying great dividends in your race performance.
Be sure to set aside time to do drills -- with
a good warm-up, long recovery interval and concerted
effort on form -- at least once a week.
Stride
drill
Objective:
Achieve 30 right foot strikes in 19 seconds.
This is an ideal cadence of 95.
Pacing:
Strides should be run at about 90% of
your max speed, not at an "all out"
effort. You should be well warmed up,
but not tired.
Protocol:
- Time how long it takes you to run for
30 right (or left) foot strikes.
- Walk back to the starting point and
recover thoroughly.
- Repeat the stride, working towards a
goal of 19 seconds for the 30 right foot
strikes.
- Complete the set of 6 to 8 intervals.

All this talk of cadence might have you pondering
that other leg of the triathlon -- the bike. Does
your cycling cadence have any impact on the run?
In fact, the answer is yes. A Colorado study actually
found that a faster cycling cadence results in
a faster run cadence after getting off the bike.
In the study, triathletes increased their cadence
and decreased their 2 mile run times by almost
1 minute (at equivalent heartrates, no less) by
simply increasing their cycling cadence by 20%.
There's your next workout. Get spinning!
