Near the end of my running route, 29 stairs loom. I can decide to smell the flowers and climb them once. Or, depending on mind and body, repeats beckon.
Up the stairs two at a time for longer strides, then a recovery down the hill to climb again.
On high energy days it's all right to run the row and go. When I'm sluggish or my mind twirls in unfriendly conversation, I go for five repeats at least.
It might take ten to jiggle the juices.
The 29 ahead alter thoughts and energy level; that's their job.
