Hey there,
I've just very randomly noticed that my heat acclimation on my edge 830 has been 0% since about last summer. I believe garmin doesn't measure and take it into account for my VO2max estimation since it's still under 21 celcius outside. However, the problem is I do 50% of my rides indoors on my smart trainer and despite the fan and the A/C, the temp. inside is always around 24-26 celcius. Thus, garmin should in fact measure and/or estimate my heat acclimation and give a VO2Max accordingly.
I found it hard to believe that garmin could not think of using the temp. data from the device itself (which would then provide the actual temp. in the room while I'm training indoors) in case of indoor cycling exercises.
Anything I'm missing?
Cheers!
