Running is great for mental health, until it gives you anxiety...

I'm back in the mile high city and still recovering from my whirlwind trip to Boston (my home town).
So when a "How to Sleep Better" click bait title popped up in my email, I indulged it.
The newest fad is something call "Cognitive Shuffling"
Basically, focus on 3-4 random words.
Mine are apple, wind, tree, and sun.
By keeping your attention on those words, you can practice blocking out the intrusive thoughts that sneak in as you lay in bed looking up at your phone the ceiling.
Interesting.
But I know another place where my mind can run wild and let negative thoughts creep in...
Could the same practice work as you stand on a starting line?
As your timer ticks down to the beginning of a tough interval?
When you're staring at the top of a hill that seems to be getting further away as you run up it?
Honestly, not sure.
But it's a worth a try!
