I do everything from gym workouts, to pilates, jogging and even Mountaineering / long hikes. My Forerunner 305 needed a chest strap, but, my newer one doesn’t (and I agree, the optical sensor, whilst I was skeptical when they were first released, are actually really awesome).
I guess I’m also a bit iffy about the battery life too. I’ll need gps tracking, strava syncing, and heartrate tracking for 8+ hours per day I guess
