I don't know what this young lady's problem is. Evidently she doesn't know that she needs to keep her arms tucked in and moving forward in order to get the maximum results for the energy she is expending. She needs a running coach for sure.

She also needs to work on her rehydration technique. If she would put a little more of that water in her mouth than down her shirt she might be less prone to cramps.  Silly lady.  If any of you see Miss Pelas, please send her my way so I can work with her on her form.
