How to set up a multi-sport activity on Vivoactive 4S

You can't. The Vivoactive does not have that feature.

Although, perhaps there's a 3rd party IQ app in the store that can do multisport.

I don't know about the badge, but I use the hMSport app from the IQ store for multi-sport activities. It works well for triathlon.

I bought the Vivoactive4S because it has a lot more features and activities and workouts that all the other watches as a general all-rounder sports watch rather than being a sport dedicated watch.

That's good for you, but how does that answer the original question?

Does that produce an activity that shows as "multisport" in garmin connect? If it does, then you should get the badge.

I am not sure, as I have configured the app to report each part of the multisport activity as a separate activity. You can also set it up to not split it, but I haven't tested that. I think each part will count as "laps" then.

Ok, then it that case such an activity won't get you the brick badge, I think.

You did not answer my original question so I have to try and figure it out myself now as no one can answer it.

You cant get the multisport badge with the Vivoactive 4s

why not?
