In the article, the author cites an extraordinary experiment in which mice were divided into four distinct control groups: The first group was placed in an empty, barren cage. The second group was placed in a cage filled with colorful, stimulating toys that would appeal to mice. The third group was placed in a cage filled with colorful, stimulating toys that would appeal to mice and a running wheel, essentially, a mouse treadmill. The fourth group was placed in an empty barren cage with nothing but a mouse treadmill.
As the experiment unfolded, it was clear that the mouse treadmill easily trumped the colorful, stimulating toys as the activity of choice for the mice. Additionally, the brain development of the mice who were caged with the treadmills was measured to be significantly better than the brain development of those mice caged without access to running. And, perhaps most remarkably, the brain development of the mice in the two cages with the treadmills was equally significant and not at all affected by the presence of, or absence of, stimulating toys. In other words, the extra stuff didn’t matter. The only thing that mattered was the running!
Of course, this got me thinking about what this might mean to us as ultrarunners. I think it goes without saying that we all have felt, from time to time, as though we are all smarter and more evolved than our non-running brethren and now, thanks to studies like this, we have empirical research to back up this opinion. But what does it really mean? And, most notably, why don’t the toys matter?
This stream of consciousness got me thinking about my favorite running experiences. Some of the richest are filled with toys: Western States, Hardrock, Vermont, group adventure runs at the Grand Canyon, in the Sawtooths, along the Appalachian Trail, etc… but most, frankly, are not. Most are simply those runs that fill out the rest of my life. The runs that get me fit, make me happy, keep me sane, and, perhaps now, make me smarter.
I suppose we need both kinds of runs to keep us going. Certainly, hours and hours in the barren cage makes the times with the toys that much sweeter. But for me, and perhaps others out there, I can live without the toys, but what I can’t live without is the running.

- What auxiliary benefits do you find running has for you?
- Are there any “toys” that do draw you to running?
