Allen, Peter is right on the mark with the strides. I used them extensively when I first started running distances 4 years ago.
I even started with shorter strides and I tried to make them more like Fartlek intervals. I would look up and say ok I am going to run with some strides to that light post. I envisoned myself running with my buddies as a kid. I will race you to the light post.
