FR 645: Lactate threshold not detected
Former Member
I have had the watch for a few weeks. The VO2 max is calculated, 48. My max HR is entered, 166. I have the HRM Run chest strap. Ran the test (for a second time (failed both)) and stayed within the prescribed zones as directed...in fact, never strayed from the zones for an instant! After the last 3 minute interval, with my throat sore from heavy breathing and my HR at 164 (close to max), I get the message "Lactate threshold not detected". What the?!?! So, what am I missing? Is there some secret setting I need to change (turn off auto detect, change my watchface?). Any help would be appreciated...thanks. At a minimum I got a good workout (brightside).
