Another great post by my coach, Matt Ebersole, of Personal Best Training. Having just run a 2.93-mile 5k, this post really rings true! Or that time my watch read 30 miles for the Monumental Marathon because it dropped the GPS signal three times (Garmin tech figured that out, and eventually replaced my unit altogether).

You know you are a GPSer if you have never run an unmeasured unrecorded mile, unless of course you forgot to charge and your battery died during the run.  If you wondered if it still counted because it was not captured on your download, you are definitely Gen GPS.

Don’t get me wrong, I use a GPS watch and enjoy the freedom of running unmarked courses and still knowing my mileage and splits.  Hey, I am an early adopter of running tech.  I started using a HR monitor in 1988 (thanks, Coach Benson!).  As a coach, all the data I can see from a runner’s workout is valuable in determining workout quality and progress.  A GPS watch is a great tool, but some GPSers don’t know the short comings and how to avoid the problems they can cause.   So from a runner that has been at it for more than a few years and a coach that sees hundreds of downloads each week, here are a few problems I see with GPS and how to adapt.
