It didn’t happen during the run. But it always happened right after the run, as I was walking through my cooldown.
This always fascinated me, and there’s probably a very straightforward explanation for it, such as increased blood flow to the brain as a consequence of running. While running, physical exertion likely commands most of the blood flow, but during the cool down, I’m sure the brain gains the privilege of some increased oxygen supply.
The most intriguing thing is how subtle this entire process is. There’s nothing that feels distinctly different – I’m still the same person, thinking in the same way that I usually do. But for some reason, I’m able to generate thoughts of a greatly increased caliber.
It’s insidious. Why? Because the converse is also true. When we’re sleep deprived, stressed, not eating well, not exercising, or otherwise not at our peak, it’s all too easy to not notice the difference. We feel generally the same much of the time – down a cup of coffee and everything’s better. But the effects are definitely there.
