Garmin Connect processes the data of an activity in many ways to help you fully evaluate your activity data.

Below are the more in depth descriptions of various time and pace/speed fields that are displayed in the details of a recorded activity:

Moving Time: Includes only the time you were moving
Time: Includes time moving and time not moving (if Auto Pause is off)
Elapsed Time: Includes time between when timer is started, stopped, and reset (includes Auto Pause or manual stoppage of the timer)
Average Pace/Speed: Pace or Speed for entire duration of an activity
Moving Pace/Speed: Pace or Speed that only includes time spent moving (does not include Auto Pause)
Best Pace/Speed: Best Pace or Speed throughout the duration of an activity

Being aware of the differences between the various timing fields will assist you in utilizing them fully in evaluating your training.

NOTE: Time, Elapsed Time and Moving Time can and often will be different. For example, if you start recording your activity at 10 o'clock and save your activity on your device at 11 o'clock, the Elapsed Time will be 1 hour, but the moving time may be less if you stopped moving at any point during that hour and the Time will be different if you use Auto pause or manually pause the timer.
