This is me today, running on the track. I intend to run 400 meter intervals for the month of August to improve my cadence and stride length before the Boulder Marathon at the end of September. I ran 4x400s today and I’ll add one more interval each Sunday until I reach 8, which is what I used to run in college, 8x400s.

This was me on the track in college, forty years ago. I don’t expect my stride length to get to where it was then, but a boy can dream.
