The "Favorites" mobile app feature is a great way to keep an eye on all the events and races occurring at your favorite tracks! The feature allows you to select certain tracks that will always show at the top of the available tracklist, so you never miss any action.
To begin this process select "Tracks" (indicated below) which is located at the base of the page. Once selected, this will bring you to the list of all racetracks available for selection. 
To add a track to your Favorites list, simply tap the grey star to the left of the track name and it will be added to your list of favorites. Alternatively, if you wish to remove a track from your favorites list, simply tap the previously selected gold star to the left of the track name.
