Following old and new friends is easy with the Zwift Companion app - and once you follow someone, it's even easier to join them for a ride!
Following a Friend (Requires ZC)
You can follow other Zwifters both on-the-go and while connected.
While you're on-the-go, you can find Zwifters who are currently riding on the Sneak a Peak screen, or you can search for Zwifters by name. To search by name, just tap the menu icon in the top-left, tap Search, and enter the screen name of the Zwifter you're looking for.
Once you've found the Zwifter you're looking for, tap their name to bring up their profile. You should now see an orange "add follower" button in the top-right corner. Tap it to add that Zwifter as a follower.
That's it! Whenever that Zwifter rides, you'll receive a notification on your mobile device (if you have that option turned on). If the Zwifter you're trying to follow has a private profile, you won't immediately be able to follow them; they will have to approve your request first.
Riding/Running with a Friend
Once you've followed a someone, it makes it much easier to find them and ride/run together. All your followers that are riding/running when you reach the Start screen will appear at the top of the riders list with a follower icon in front of their name. Just click their name and choose Ride/Run with "Name." When you join, you'll show up on the course at their position.
Note: you will only see followers for your selected sport.
