I follow my garmin suggestions occassionaly and on this occasion when I selected treadmill run it suggested that i was due for a VO2 max run.
So it suggests 10mins of a warmup run and then a series of high intensity intervals at xx speed for 3 minues and then a lower intensity speed at xx for 2 minutes in between followed by a 10 min warmdown.
The issue is that on a treadmill it estimates your speed not by GPS but your arm movement which i have to say has been rather accurate in regards to speed/distance on a normal treadmill run. However, I think it must use some sort of average to estimate your speed because as soon as i ramped up or down it would take aobut 1 to 2 minutes to start reading my actual speed.
Normally, I would just put this down to a limitation of the watch but there are a couple of things here.
1. If its not a bug and actually a lmiitation then dont suggest this sort of run for a treadmill
2. The fact that it couldnt track my run correctly it basically thinks i have declined in fitness. It put my training status into Unproductive and has now adjusted my training program. My base run speed has been lowered and VO2max score was adjusted as well as other things that I probably dont know about it. Even though i removed the event from my watch 1.5 weeks later my levels still have not returned back to where they were.
