The "new" feature that tells me I am behind range 30 seconds into my warmup is annoying. And then when doing 60 second speed repeats on the track to have my wrist vibrate after 45 seconds because I am ahead is a distraction.
I want to be able to turn these on and off.
OK I have an Apple Watch and not a Garmin device but the principle is the same; these are useful features sometimes but the terrain and situation vary making the switch from pace (or power) to PE necessary.
I have searched everywhere and nowhere is there any indication of how to toggle this. My solution for now is to manually widen the ranges on my program.

TreaningPeaks has nothing to do with that. I contacted Garmin in regards to this issue (it used to drive me crazy but I learnt not to pay attention) and Garmin informed me that alerts cannot be turned off in scheduled workouts.
