20 Minutes Threshold, ( 6.5 Miles Total)
I'M gussing the distance today, as I ran an out and back from Newbury along the towpath with the M.P.U. in my older NB 832's. Details below:
13 Minute Warmup (HR Avg = 145)
20 Minutes Threshold (HR Avg = 171)
13 Minutes Cooldown (HR Avg = 154)
20 Minutes Threshold (HR Avg = 171)
13 Minutes Cooldown (HR Avg = 154)
I tried running with my leg in a permenant state of plantar flexion to encourage running on my toes, a potential improvement in my form suggested by the level 4 (?) coach who performed my video analysis at the club last night. I can see how it's more efficient; as my achilles tendon is assisting my rebound off the ground (the joys of plyometrics, eh?), my quads aren't tired from having to push me off. This allows me to have more of a knee raise element to my stride. In practical terms, I was actually struggling to get my heart rate to elevate whilst running like this (it's like free money, speed for nothing!), and by the end of the run it felt quite natural(ish). It certainly reduced the strain on my knees, however all was not universily good with it. My medial shin area attachments certainly felt a little beat up after the run, which wouldn't suprise me, as they would be under greater tension than would be caused by my normal running style. That doesn't necessarilly mean I should bin the form improvements, it just means I need to be careful, as I'm obviously going to have to take my time in decongesting & strengthening that area if I'm to avoid injury in the transition. I will consult Barry & Martin before I go any futher with this though... Show/Hide this post [+/-]
