Is that an average for the time for a mile. I have two workouts exactly the same (similar if they were exactly the same there would be no difference!) except for one was faster but it shows a lower figure. First trip is 13:52 second trip is 13:12.
If this is pace then 13:12 mins per mile is faster than 13:52 mins per mile. If speed, then it's the other way round - 13.52 mph is faster than 13.12 mph
