I have been using the Edge 540 for the last month and have logged at least one activity nearly every day over that period, so there is sufficient data logged to establish a normal load range. However, nearly every ride I have done shows the primary benefit to be "base" and low aerobic. Even doing sprint interval workouts where my power is zone 6/7 for 15-30 seconds, with 5-10 min warm-up/cool-down, so no excessive Z2 tails. I ensured that my FTP and LTHR/Max HR were set correctly on the device as well.
I am trying to determine why I am not getting any anerobic or high aerobic as the primary benefit on these rides, particularly when doing more intense sprint or sweet spot workouts.
