BQ by 40

Usually, I'm able to pad 6 extra miles by running down the sidewalk on Bardstown Rd early (before each business' driveway has cars going in and out). Not this morning. Summary Stats:

...It seemed a little breezy out there.

I started having trouble around mile 15 of my run, but I managed to not walk even when it didn't feel like I was running anymore.

The 'X' near the top of the map is where I got confused (at around mile 15) and missed my turn. I've been through this neighborhood for every 20 miler I've run. Obviously, my brain was overloaded at this point.
