When I run in the interval training mode I find a disagreement between the laps time and the laps pace. For example, yesterday a ran 1 km 5 times with 3 minutes recovery between each kilometer (after a 10 mins warmup). When I downloaded the data on my PC, in the column "time" I read 4.30 for the first kilometer and, for the same kilometer, 4.27 in the column "pace". Shouldn't they be the same? This happens for alla laps. Pace is always faster than time. I have a Tomtom spark cardio+music.Thanks very much.
