As I've progressed as a runner over the years, I have also developed more and more as a student of the sport and I must say I really enjoy learning new tools to fuel this passion that I have. Of course, when I say I'm a student of the sport, I mean that I study it in my spare time. Contrary to popular belief, I didn't go to school for running. No, I actually received my degree in Civil Engineering... something I pursued in my first year following graduation, but have since set aside to entertain other pursuits. For the better half of my undergraduate studies, my concentration was Structural Design. In all my structural specific courses, there was a common term that was applied in every design situation, which we knew as the Factor of Safety.
The Factor of Safety is a variable that refers to how much over engineering is built into the design of various structures to withstand above average loads. This number varies based on many outside factors including cost, weight, climate, and so on... but the largest determining factors come from the variability of the building materials and the consequences of failure. For example, the elevator in your workplace probably has a Safety Factor of 10 or more. This means that whatever the maximum expected load is, the structure is built to withstand 10 times that load. This is not because there is a high variability in elevator materials, but rather because the consequence of failure (loss of human life) is extreme!
As for building materials, you can expect a lot of variables in material strength. For example, the tensile strength of steel is very high, but steel is also very heavy (~450 lbs/cFt), while the tensile strength of concrete is very low but it's compressive strength is high and it has a relatively low weight (~150 lbs/cFt). Furthermore, the consistency of materials like concrete and wood vary much more than that of steel, which causes it's failure properties to fluctuate, which again would raise the necessary Factor of Safety to account for these less predictable characteristics. This is why you typically see structures built with a combination of materials to accommodate the different forces in which that structure demands, while also meeting the practical demands of costs, weight, and functionality.
In this same school of thought, our bodies are designed in a similarly engineered fashion. We have a heavy bone skull to protect our most valued organ; we have larger bones to support the larger, harder working muscles; we have strong elastic tendons and ligaments to connect all these moving parts; as well as a flexible, fatty flesh to pad our exterior. Much like the many variables of building materials, we also find many variables within our body components. Some of these variables come from predisposed genetic features; giving us different body structures, deformities, diseases, and so on. Other variables come from what we do with our bodies after we're born; the types of food we eat, the amount of exercise we do, the drugs we abuse, the strenuous demands that we put on our bodies, and so on.
As incredible as these miraculous human components are, the average body is not built to withstand over 100,000 miles of intense running. Some people can do it, but it takes more than just a cushioned pair of shoes to do so. Again, like the "born with" material strength of wood and stone, we also have our own "born with" properties that we have to work with. As much as our elementary school teachers would like us to believe, we can't go out and build bridges out of toothpicks or houses out of gingerbread, regardless of how much super glue or icing we use. Similarly, I know I will never be able to run 9.58 in the 100m or 12:37 in the 5000m, regardless of how hard I work at it. I don't want to put limits on myself, but I know enough to realize those tasks are reserved for the "un-human" likes of
Usain Bolt and
Kenenisa Bekele.
Knowing that my body was not designed for all the tasks that I ask of it as a runner, I know I need to supplement my training with more than just ball-busting intervals on the track. I need to increase my material strength in order to withstand the forces that I hope to continue for a while longer. The question is how strong to make it? With so many variables within each athletes body and so many variables with how much stress we put on that body, it would be impossible to predict the exact point of failure for each bone, muscle, and tendon in the body. Therefore, we over engineer and we make each component able to endure more than we expect of it. By doing this, we increase our "Factor of Safety" and reduce the chance for failure (even if we encounter an above average load). Because I have been vulnerable to injury in the past, and the consequences of getting hurt are pretty severe for me, I plan on doing more "over engineering" than I have in the past. With that, I hope to stay healthy longer, get stronger, and ultimately get faster.
I've done various types of supplemental strength training in the past but have never had a structured routine or schedule to stick to. Instead, I've just used the "I'll do it when I can" mentality. I'm trying to change that by creating a routine that works for me and stick with it. The best core strength routines that I've seen to date have been those described by
Coach Jay Johnson. He demonstrates some of these in
this article with Running Times and I've linked a few of the videos in my training below. However, the more extensive exercises can be found on his
DVD set. I have just started to implement these more structured routines over the last couple of weeks. It's something that takes time and I need to make sure I set aside the time to do it. As you can see, my mileage is pretty low right now and it was still tough to get everything in. As I continue to add mileage and intensity, it will be even more important for me to schedule my day around my runs and all the supplemental work that goes with it. All this in addition to some other drills, core work, rehab work, massage, and good nutrition will hopefully add to what I'm trying to accomplish. If I'm gonna do this, I might as well do it to the best of my ability. It won't be easy and I'm sure there will be more difficult choices ahead, but if it gets me close to where I want to be, it will all be worth it. Despite the set backs and aggravation, I continue to believe that this is a structure worth building!

In other news, I'll be heading out to Oregon tomorrow to take part in the
Hood to Coast Relay. I was able to get this all expense paid trip through my connections with work and with
Strands. I think it will be a great experience and a good chance to catch up with old friends and expand my connections within the running community.
More when I get back. Stay tuned.
