bc can't read.

p.s. When you are jogging at constant speed, I suspect that a large  
fraction of the work you do is pushing your center of mass upward,  
giving it the energy to reach a peak height, an energy that is then  
lost in the inelastic collision that occurs with each footfall.  So  
the work done in each stride is proportional to your weight and the  
change in height.

Philip's answer I think is it.
