I just did a lactate threshold test for the run. I did the 30 min. TT and hit the lap button @10 minutes. The results don’t make much sense to me.
Entire 30 min: 170 max, 159 avg
1st 10 min: avg 150, end of lap 164
last 20 min: avg 163, end of lap 164
I took frequent looks at my hr during the test and the highest I saw was 159 in the last 4 minutes and at the end. In the 1st 10 minutes it got up to about 152. During the last 20 minutes, it gradually creeped up to 159. I would guess I averaged 155-157 the last 20.
I don’t understand the discrepancy between the numbers I saw while running and the numbers my watch says now.
Needless to say, I’m damn frustrated right now. I hate the idea that I went through that pain for nothing.
Any ideas? Anyone else had this problem with polar? I used a Polar S120.
I’ll probably post this @ Gordo’s site as well as it’s heavy on training/testing issues.
