I just hiked 6.11 miles with 1454 ft of elevation gain and my Garmin Instinct tactical only counted 252 calories and a ave HR of 68 with a max of 1033 bpm. The distance and elevation gain are pretty accurate, but the HR reading and calories are way off. I was in the hiking mode, but not sure that should make any difference. Does anyone have any thoughts? I purchased the watch mid Aug of this year.
