When running a workout with an interval with a target pace, I notice that the elapsed time for the interval is considerably higher than the pace measurement ever reaches. For example, I'll run an interval with the target pace between 7:30 -7:50 and as I watch the pace, it'll never exceed the range, however when the interval ends, the watch will show an elapsed time of 8:00+.
Is there a reason for this discrepancy and will I need to just offset my target pace range by 10 or so seconds to account for this going forward.
