Many of the Thanksgiving traditions of my family are over 30 years old: the meal with the brothers at the oldest’s house, the flag football game, the day after hike, guests from near and far. Many of the children who are now parents don’t really remember Thanksgiving any other way. But as spouses have been added, which means extended families, the traditions have had to flex and bend to traditions and schedules of other families. The day after hike used to be on “Black Friday”, sort of a rejection of the shopping madness for a stroll in the mountains and conversation with family. But this year and last the big meal was on Friday, and this year the hike was on Thursday. Rather than brothers and spouses and children and cousins, it was trimmed down to my oldest brother and me.

We explored a few ruins and cemetery in the Sugarlands of the Great Smoky Mountains National Park. There was once a thriving community on this gentle slope below Bulls Head of the Mt. LeConte. The sugar maples upslope were a source of sugar and the name of the community. There was Pi Beta Phi settlement school begun there in 1920 with a stone house for the teachers and later a CCC Camp for workers in the young National Park.

After the hike I went to visit my 3rd born. Arriving just before dark, we went down to Kingston to see the sunset. Having already set, we walked the concrete “boardwalk” enjoying the fading colors and good conversation.

On Saturday I went bouldering at Lilly Boulders at the Obed Scenic River climbing area. I was by myself at first but met up with another climber with whom I enjoyed the day. I was climbing exceptionally well, and truth be told, the grading of climbs seems easy here than at home. The day was perfect for climbing: crisp, dry, sunny.

Equations are abbreviated definitions that simplify and  clarify complex concepts and data. They may be used to calculate, which may either reveal past events or predict future outcomes. Qualitatively, they enable the understanding of interrelationships between variables, which may not be obvious otherwise. On the other hand, not all relationships within an equation are the mere product of their juxtapositions within an equation. Rather, some variables owe their interaction to feedback loops within their physical situations. For instance, according to the equation below, in order to have the best period (race time), both power and endurance must be at their maximum. But in physical reality, for a runner, when power is maximum, endurance must be low. Sprinters are not endurance runners. Conversely, when endurance is high, then power must be low. Long distance runners are not sprinters. Actually the equation does reveal this relationship, because if you move the power variable to the other side of the equation you get po = 1/e, or more accurately, power is inversely proportional to endurance. That is, as endurance increases, power decreases.

From the equation you may also see that pace and distance should be inversely proportional. But the opposite is true. A longer distance requires requires a slower pace, that is, larger number.

And when distance is increased, endurance must increase and power must decrease.

The Runner efficiency variable may not be able to be determined, though I think that athletic physiologists are trying desperately to do so with VO2 max, respiratory exchange ratio, fast twitch/slow twitch muscle, body mass, % body fat, and running mechanics. Strength training and anaerobic sprints seem to be two popular methods for increasing runner efficiency. Diet must not be discounted as a way to build better runners.

The constant, K, is a factor that converts the other five variables into a race time, T. At this level of development of the equation, it is nothing more than a fudge factor to make five variables equal to the one.

The best race time (T) is what every runner, coach, and spectator is after. Thinking through this equation might help the runner and coach better design training that will secure that result. Are you training for power, the sprint, or endurance, the long distance run? What training regimens do you need to perform to meet these goals? How much is it reasonable to increase both power and endurance? What are the limits of one, given the other?

I feel certain that good runners and their coaches have all of the relationships dialed in, so that an equation seems silly, but I benefit in my thought about running by the simple definition called an equation.
