A Perfect Run
Monday, July 12, 2010 at 10:14PM
Why is it that some days a mile can seem daunting after taking just a few strides? Yet during others your legs feel like pure iron, your stamina tank appears bottomless and you seem to invoke the spirit of Forrest Gump?
I recently had one of those perfect runs. Like the unforgettable vacation you always strive to recreate, I setout to deconstruct the factors contributing to my run with the hopes of discovering the optimal, fundamental conditions that led to my quintessentially perfect performance.
Through my self-reflections I’ve identified 5 key elements: sleep, diet, time of day, weather and rest. And rather than merely speculate that these factors played a significant role in helping me achieve my ideal running state, I sought some evidence to support my hunches.
Sleep. Although I had every intention of waking up with the alarm at 7:30 AM to run with the Elysienettes, I smartly and decisively shut the alarm at 4:30 AM after suffering from a restless night’s sleep. Even though waking up to my unknowing husband anxiously declaring, “It’s 8:15 AM, babe!” wasn’t the most harmonious way to arise, at least I was able to clock 8-hours of sleep.
Turns out, those extra 45 minutes may have had a significant impact on my endurance. According to a recent study published in the European Journal of Applied Physiology, one night of sleep deprivation was found to decrease endurance performance.
Diet. Earlier that morning I fueled up on two poached eggs and a multigrain English muffin – a healthy combination of complex carbohydrates and protein. Countless reports suggest that proper diet is one of the key components of running and must include: carbohydrates - which turn to glycogen and serves as the primary energy source for our muscles, protein to build and repair our body tissue, and water for obvious reasons.
Just how much of the primary food groups should runners consume? Mindy Solkin, a certified USATF coach recommends a diet comprised of 60% carbohydrates, 15% protein and 25% fat.
Time of Day. I’ve always known I’m not a morning person. All night-before-resolutions to “run before work” have resulted in my resetting the alarm just to get that extra hour of sleep. Rather than continue to set these unrealistic expectations, I’ve embraced my nocturnal tendencies and decided to run most nights after work. Still, my energy levels often feel depleted by 7 PM.
Then there’s Saturdays, early-afternoon. After a solid 8-hours sleep and gradual awakening, I can feel the energy bursting within me, and with ADHD-like vigor I begin bouncing off the walls of our 500 sq. ft. apartment.
Not surprisingly, this is also when I’ve experienced my strongest running performances. Evidence suggests that our body temperature peaks in the mid- to late-afternoon, which results in easier running and increased lung capacity.
But not everyone is best suited for this time of day. Nick Morgan, a Running Times contributor, indicated, “A more likely explanation is a perfectly natural phenomenon known as circadian rhythms. These are small fluctuations in the performance of bodily functions on a 24-hour basis.”
Weather. For anyone who’s ran in the 90 degree heat or pouring rain, it’s clear the weather can dictate how we perform. During my “perfect run”, the weather was cloudy and 71 degrees with a cool breeze coming off the water and pre-storm-like ions buzzing in the air around me. Needless to the say, the conditions were ideal.
Interestingly, these temperatures could even be considered high. According to Dr. Andrew Schneider, “the perfect running temperature has been scientifically debated to be somewhere around 50-54 degrees. Most people begin to slow after 55 degrees and can really "hit the wall" if the temperature rises above 65 degrees while racing.”
Rest. One thing is indisputable: our bodies need rest days in between training runs to improve performance and reduce the likelihood of overtraining and injury. How “rest” is defined, however, is debatable.
For me, I’ve incorporated a full rest day (i.e. doing NOTHING) on Fridays to prepare myself for long runs on Saturdays. But for others, rest may imply cross training exercises including biking, swimming or stretching. Hal Higdon, author of Marathon: The Ultimate Training Guide (and my all time idol) reiterates the importance of rest throughout his book and encourages runners to avoid all activity on designated rest days. Depending on your running abilities and training goals, rest days range from 1-2 days per week.
Incorporating these ingredients to create the “perfect run” requires discipline and determination. Whether I’ll ever get back to that state of running euphoria is beyond me at this point. What’s in front of me is being prepared when the moment comes.
