Hi guys, last weekend had opprtunity to test both during Julian Alps Trail ultramarathon. One is my track witch Epix 2, second one is my friend with Fenix 8.
Main conclusion for the moment: Fenix 8 still needs lots of software improvements to reach Epix functionality during races. The rest is inside:
Epix2 track: https://connect.garmin.com/modern/activity/17097721662 24:32, battery drain circa 60% (1 year old, 4-5 activities per week)
Fenix8 track: https://connect.garmin.com/modern/activity/17097746487 20:19, battery drain circa 35% (first ever usage, so the battery is new)
Check the altitude difference: Epix is 4894, Fenix 5200 - official track was circa 4860 so Epix is more right.
