Not quite sure where I’m going to go with this, but along the way, I’m going to take some notes.

Running is something that I’ve long done, but without having given it a whole lot of thought.  Let me restate that: it is something I’ve done without analyzing it as much as I might ordinarily analyze things.  Let me try that again: … without having talked as much about my analysis of it.  That’s probably because most of the analysis has been something to keep me busy on longer runs, and has been in my head (and mostly without a spreadsheet being involved! – noted emphasis on “mostly”, rather than on “without”).

The thinking has generally been around foot plant, leg movement, energy and efficiency, translation of forces, performance… It really all began when making subtle shifts in center of mass and body angle, in order to give tiring parts of me a break – so I could make it all the way home. This evolved to trying out variations of foot-plant; softening ankle, knee and hip joints on impact; and even to deliberately reaching for heel plants to see if beginning some backward foot motion just prior to impact might give some pull-power (the way toe-clips for biking enable capturing the upward leg movement when driving the pedals around, to contribute to forward force and movement.

The experimentation wasn’t particularly scientific, and the most memorable observation was of a different kind of tired (specifically in the hamstrings). Next up was a little reading about Pose and some deliberate forward tilting and intentional toe-heel planting.  Beyond being a little awkward and almost confusing to the subconscious, I recall the lower legs taking quite a beating from that experiment.

Over time, I’ve evolved to a quiet and soft, mid-foot strike which seems to have served me well.  But I’m thinking more about what’s being left on the table.
