Favorites will be displayed under the "Racing" tab, and then on any of the tabs under horse racing, you'll see a section labeled "My Favorites", from here you'll be able to see your favorite selected tracks!
You can add favorites by clicking the "grey" star on the left-hand side of the track name. You can remove favorites by clicking the "yellow/gold" star in the same place.
If you have any questions or concerns regarding favorites, please email us at Support@TVG.com, or click the "Message Us" button from the support center.
