An interactive television application allows a viewer to track the progress of participants (110) along a course (100) in a sports event. The location of the participants is tracked, such as by using a GPS device (160). Data is provided to the application to provide an on-screen display (310) of a graphic (700) that shows the distances of different points along the course and the locations of the participants. The graphic is updated to show changes in the locations. Information regarding the course, such as difficulty (500) elevation (500, 600, 700) and weather conditions (700) can also be displayed on-screen. The viewer may also select participants to follow, such that other participants are filtered out. Furthermore, different camera feeds (120, 150) are associated with the participants such that the viewer can elect to view the camera feed of a selected participant.
