In this type of stride, the hamstrings get over-used pulling the body forward over the forward foot at initial contact. There is a shift in where your overall forward movement comes from, making it come more from your hamstrings pulling you forward (kind of) instead of it coming from your glutes pushing you forward.
Thanks Wahine, I am going to have to think about this but I understand what you are saying. I am going to experiment again with trail running on Sunday and I will see how things go. I have noted that it takes much longer to bother me on dirt. Given the source of my ankle inflexibility, is there really anything I can do to help this? I do a ton of ankle mobility work that has, over time, helped both my ankle and calf out a lot. I will also also try to be mindful of just where that left foot is striking in relationship to my body.
