My Experience
Real numbers from real tracking — no guessing
WHOOP 4.0
Since 2022
Daily WearWHOOP is my go-to for understanding recovery. The recovery score tells me whether to push hard or take it easy. The sleep tracking is unmatched — it knows when I'm undertrained before I do. The lack of GPS doesn't bother me since I use Garmin for running.
Garmin Fenix 7
Running & cycling
Garmin is my workhorse for outdoor activities. The GPS is bulletproof — never loses signal, even in dense tree cover. Battery life is insane; I can do a 50-mile ultramarathon without worry. The Connect app gives me every metric I could want, even if the UI feels a bit dated.
Apple Watch Ultra 2
Everyday & workouts
Apple Watch is my daily driver for non-running days. The display is gorgeous, notifications are seamless, and the ecosystem is unbeatable if you're in Apple land. But the battery life is a real limitation — I charge it daily. For serious athletes wanting battery, look elsewhere.

I wear WHOOP 24/7 for recovery and sleep tracking. When I go for a run, I grab my Garmin Fenix 7 for GPS tracking. Apple Watch handles my everyday notifications and non-running workouts. It's more gear than most people need, but each device excels at its specific role.
