For years I have used the Fenix 5 (or maybe its 3) watch and done HIIT Training between a treadmill and weights. I would log these workouts as cardio, and manually record the distance in my app. All of a sudden Garmin, for no apparent reason, has removed the ability to log distance in cardio activities? Why?
I have in the past tried to use the so called "Multi Sport" function and its really just difficult to use, difficult to get data from, and too much button pressing between sets. The multi sport for HIIT training is just terrible.
I don't know why Garmin removed the cardio distance option but I wish they would put it back.
