So if it was really 3.1 miles I think I did really good. Could it be my Garmin was not accurate due to all the switch backs?? Anyways I had a blast. I should do more trail runs!!!

Congratulations! Trail runs are going to be somewhat to way more slower than a road race.

If your Garmin is set to smart recording (some have this option), a singletrack course could easily measure short. It's easiy for the recording point of your GPS to not record every single link twist and turn of a singletrack anyway, but smart recording makes it worse.
