I just went for an interval run scheduled in my coach plan and got a really low score of 8% and I do not understand why. I thought I executed the training pretty well and was really surprised when I got a score of 8%! This is not the first time, it seems every time I do intervals I have a bad score, what am I doing wrong?
The plan was this: 15 min warm-up @ 6:00, 9x0:40@3:45 and finally 10 min cool-down @ 6:00. I did about just that. Could other parameter such as heart rate or load impact the result? I am pushing too hard?
Any insight would be appreciated.
