Can I cut into segments?

It's difficult if you didn't record it as a multi-sport event. If you want to attach your file to your post we might be able to make it happen.

Attach your fenix to a computer, then look for the activity fit file in the \GARMIN\ACTIVITY folder. Then...

• Zip the file, then in a reply post Insert >> Image/video/file >> click Upload >> browse for file >> OK.
• Or upload the fit file to a reputable file sharing service, such as OneDrive, Google Drive, Dropbox, make the file public, then paste a link to the file in your post.
• Or if you'd rather your activity remained private, you can send me a private message.

Check out my open water swimming activity on Garmin Connect. #beatyesterday

Need your fit file. See 3 options in my previous post.

Check your email...

Actually it is easy to do in connect. There is an option to split an activity into multi sport and assign a sport to each segment. 

That's true.

I received your fit file. Since it wasn't recorded as a multisport activity, your best bet is to do what razmichael suggested...

As for what you did wrong, make sure you start your triathlon using the Multisport activity on your watch. I assume you normally do some training sessions (brick) using this, so you could test it before the next triathlon event. Mentioned earlier by Wolfindal
