Interval training 200m x 10

In my last two interval training, I go for longer distance. But then, the pace dropped. Therefore, I want to go back to go for a fast pace interval.



I shoot for 5:00 pace for 200m x 10 with 1 min rest in between. When I run, I check my pace on the watch. The pace is reasonably good starting from sub-4:00 to right around 5:00 with some extended to 5:10. However, the record a much slow pace in the SportTracks software. On the other hand, my walking break are shown faster than what actually is. I think it is due to the averaging applied by the software. The show interval splits are not as accurate.
