(Somewhere in LA, a couple Andrews Sisters are rolling over
in their graves right now.)
I discovered something interesting the other day… Studying
the data produced by Runkeeper for my last few runs, I noticed a pattern: my
pace during run intervals is all over the place – 12:48, 10:17, 11:22, 9:55… it
changes by the minute! Why would that
be? It always feels like I’m running a nice, even pace…
I thought and thought, and then it hit me – music! It seems my cadence matches the EXACT. RHYTHM.
of whatever the shuffle turns up on my iPhone.
Metallica’s “Master of Puppets” playing? I’m running a precise (and INSANE!) 220 steps
per minute. Florence and her Machine step
in with “Dog Days Are Over”? Yep, I’m
magically transported to 150 steps per minute.
I don’t know why this surprises me. After all, I more or less go through life in
eight-count rhythm. For real. Apparently my many years as a dancer have
resulted in some sort of mental metronome.
I regularly find myself mentally tapping out a beat while preparing
breakfast, taking a shower, typing, even reading. “One, two, three and four, five, six,
sevennnn, eight,” as I crack an egg, stir it with a spatula and pop two slices
of bread into the toaster.
And oh yes, when I’m running you better believe I’m doing so
“eight-to-the-bar.” Which, by the way,
makes it really hard for this math-challenged lady to calculate cadence; my brain
counts in eights, but I lack the skills to figure out on the fly just how many
steps per minute I’m running if I’m doing seven sets of eight steps in twenty
seconds. (I’d place this type of
equation right up there with the classic, “If two trains leave their stations,
one in Philadelphia and one in San Francisco… makes my brain hurt.) So I instead try counting by tens and
routinely get lost somewhere around 40, when my inner rhythm section valiantly pulls
me back to whatever music is being pumped through my headphones.
I’ve pondered this for a week and, aside from making for an
interesting (to me, anyway), blog post, I see the potential to make this idiosyncrasy
work for me: what if I were to stack my running deck by creating a race-day
playlist with musical selections that result in the perfect cadence for every
portion of the run? Some slower songs
for miles one and two, somewhere in the 150-160 beats-per-minute (BPM) range to
force an easy, relaxed warm-up pace… then bring in a nice medley with a
consistent 170-180 BPM for endurance through miles three through eight… and
finish strong with the power of a solid 182-190 BPM over the final two miles… Could I possibly create my dream race through
music selection alone?
Seems plausible, so I’m going to test it out! Hopefully with some help from a few DJ and
musician friends, I’ll try to piece together the Perfect Playlist for the Tower
of Terror 10-Miler. I’ll be testing it
out over the next two months and will report back on my findings.
