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.
