Ok I can understand that…I can honestly say that I tend to over analyze and all of those problems you just named describes me very well lol…I would reach for the ground/next stride, then I would try to hard and push as hard as possible which resulted in alot fo back kick, and I would consciously lift my knees which would cause my stride rate to decline…So in short I HAVE PROBLEMS LOL :-)…When I just focus on running with a natural and under control stride(not to much pushing/back kick and no reaching for an increased stride) I run faster and more consistently…What is digging?
