6 Miles untimed, containing video analysis
WELL tonight I ran around 6 miles in the environs of Prospect Park in my older NB 832's and for large sections of my run I was on the track, for reasons I will go into below. I generally kept my heart rate low (~150bpm) but the video analysis necessitated I did do some fast running at some points, so I obliged by striding out for the odd 200m stretch. The way I figure it, the minor change from my schedule is an investment worth making for the payoff (i.e. the data from the video).In essence, the procedure consisted of me 'training as normal' with our club's most expert endurance coach, Roger, videoing & observing me. Then, after I was finished he filmed me doing some 'run throughs' in three states. Normally, barefoot & with improved technique -specifically the footstrike element. Roger is going to edit the footage, and run through it with me next week, also giving me a DVD to take home for future reference.
The key thing Roger observed was that I am afflicted with the signature biomechanical of the modern age, specifically heel-striking (which is engendered by modern running shoes). Now I've always been away of this, but I was never aware that it is realistically possible to change it. During my last set of run throughs I concentrated on plantar flexion of my feet & it did seem easier to run fast! I do worry a little bit about taking on the new technique to rapidly though, as it does seem to require high lower limb strength & suppleness to maintain for any significant length of time, at least in endurance running terms. Of course, my fears are exasperated by my history of lower leg injury, that I had an anterior compartment release operation to correct the causes of earlier this year. I truly wouldn't want to aggravate my shins to that extent again, it was not pleasant. That's not to say I'm adverse to the idea of improving my efficiency - it's like money for nothing, speed gains without having to gain fitness! I'm just going to have to be careful.
