Was a bit shy of 8 miles...bummer! Here's the stats...
Conditions - sunny & 46
Total Distance - 7.8
Total Run Time - 1:28
Pace - 11:16
So I pretty much maintained the pace I wanted. I wish I had known I was short of the 9 miles, I would have kept going. Thanks to bunnygirl who suggested using g-map before heading out. I may not memorize the location of each mile, I will be able to 1) make sure I know the distance of my run beforehand and 2) remember the 1/2 way point if it's not an out & back route to know if I have a negative split.
