Where did I run today today ?

Yes I run.  This graph is from today's run in Arroyo Verde Canyon. These trails are used by the Ventura Cross Country team. You can see on the graph my pace along with the elevation gain and loss. They (of course) align. Elevation gain...I run slower. Down hill or flat...I run faster.
BUT now how did I get this information? We all know and at times are afraid to admit it, but we have tracking software in our pockets (running shorts). So hats off to the nerds! down with conspiracy theory.  Let's take advantage of of those little cigarette size boxes (what's a cigarette?).
