Vibrations for alerts during workout

Hello, I've been using a forerunner 245 for the past 5 years and want to get the vivoactive 6.

I use the run/walk alert on my current watch and get count down beeps and then a vibration to let me know when to run or walk 

I know that the vivoactive doesn't have a speaker so it won't beep, but do the vibrations still count you down? I like having both because I sometimes can't hear the beeps over traffic or miss the vibration because I'm on rough trail. 

If the vibrations do the count down I'd be less likely to miss them if it's multiple vibrations instead of just one

Can any one confirm?

Thank you
