Update...I think I figured out the REAL reason my pace indoors is so god-awful. Apparently there is a way to completely shut the GPS off on my Garmin Forerunner. I didn't find this out until yesterday. Up until now I have been plagued by a Garmin that randomly will connect with satellites, then my "speed" drops to 2-5mph for a few seconds, several times each minute. This was murder on my pace. So what should have been 14-16mph was showing as 12-13, most of the time.
