After three months of daily use, the Garmin Forerunner 955 has become my go-to fitness companion. Coming from an Apple Watch, the sheer depth of data blew me away—especially tracking VO2 max and run power post-workout. The Garmin Coach feature is a game-changer; following its 10K plan shaved 30 seconds off my pace, leading to a personal record. The training readiness score? A lifesaver for this overzealous runner, preventing burnout with eerily accurate slow-down nudges.

The battery life is *chef’s kiss*—over a week on a single charge, putting Apple to shame. The touchscreen is responsive, though I mostly use buttons (old habits die hard). Race day magic? Input your target finish time, and it guides you like a virtual pacer. But beware: the chunky design (I’m petite) makes sleep tracking impractical for me, and it’s no smartwatch—text replies require your phone.

Minor gripes include occasional software glitches (that stubborn blue triangle) and bulkiness. Yet, for triathlon training (despite lacking integrated tri plans), GPS accuracy, and metrics galore, it’s unmatched. If you crave data over texts and can handle the size, this watch turns you into a disciplined athlete overnight.
