You.. Dont need to root your device to install a custom rom?
You can very well unlock your device, flash a custom rom, and use it unrooted. Nowadays quite a lot of custom rom come with a kernel prepatched for KSU, but that's obviously not a requirement..
That's great! Idk if there's a way to automatically sync the garmin with it, but I use Fitotracker, and app on my smartphone, and it works great! If you dont feel like selfhosting your own instance you can use mine, workouts.estebiu.com. But again, don't trust strangers on the internet.
