In the last weeks the range for this kind of workout has been raising. It was between 119 - 136 2 weeks ago, and under 132 bpm one month ago
I had a 5k race last saturday and the threshold was raised ( I did not perform well in my test week so it was expected )
what I didn’t expected is the range of aerobic development being raised again to 126 ~ 145 bpm range. I definitely can run for very long at 145 bpm, but at 145 I have the feeling it’s more L3 than L2. For now I keep it around 132 that’s how I feel it is very easy.
is it the right way to interpret the range ?
