Geocache Is Not At the Posted Coordinates

Josh is a cross county runner. He can run a mile in 7 minutes and 51.4 seconds. I wish I was even half that good. After asking Josh to help me with my training, I seen my times improving. It is a tuff workout but a simple training routine that most of us can follow.
After working out with him I am proud to say that I can now run a mile in 8 minutes and 12 seconds.
Woo Hoo!
It is now time to solve the puzzle. After you solve the puzzle maybe you can time yourself at running a mile and post it in your logs to compare yourself with josh.
