Before I bought Forerunner 265, I read that heat acclimation is available on 255, and assumed that it will be available on 265 as well.
It turns out that this feature does not exist on Forerunner 265, and was disabled on 255 as well.
As I understand 265 has the required sensors for 265, so it's related to software only.
Does anyone know if Garmin has any plans enabling it on 265?
