Pace discrepancy in the Fitbit app.

[TUDJR]

I am a FITBIT IONIC user and just competed in a charity 5k.  I used the exercise tracking on my iphone FITBIT app in order to get my pace notifications along with a map and splits.  The total time was off by 1 second (understandable), the distance was off by .163 miles (5%), but the pace was off by almost 1 minute ??? Can someone please let me know why this is.  during the event i though i was doing better than i actually was.........  this was my first 5K and want to know what i should do for the next one.

i have pictures of both my excercise (fitbit app), and my official race results but could not upload here

thanx

Hello @TUDJR, I hope you're doing well, it's nice to see you around. 

I appreciate you have brought this to my attention and for attaching some screenshots to your post. To clarify, did you use the integrated GPS on your Ionic or MobileRun in the Fitbit app? Or, did you use both at the same time? If you used both at the same time, I would like to suggest you to only use one, preferably the Ionic, as it has integrated GPS. 

Take in consideration that Fitbit devices calculate distance by multiplying your walking steps by your walking stride length and multiplying your running steps by your running stride length. We estimate your stride lengths using your height and sex. When you use your Ionic and track one or more runs using on-board or connected GPS, we evaluate that data to automatically update your running stride length. For best results, run at a comfortable pace for at least 10 minutes.

If you prefer to measure your walking and running stride lengths yourself and enter them manually, see How do I measure and adjust my stride length?

Note that when you're tracking an activity with GPS, Fitbit calculates your distance using GPS data rather than steps. If you begin moving before you get a GPS signal, the tracker will calculate distance using steps and stride length as described above until a GPS signal is found.

I hope this clarifies this situation, if there's anything else I can do for you, please feel free to reply.

I used the gps on the Fitbit app for this race. Thanks for the feedback. I will try the onboard gps to track the next race and see what I come up with. I will also check my walking stride and adjust if necessary. Once again thanks and the info is much appreciated.
