Here is the latest television schedule for horse racing related programming. All times are in Eastern so check your local listings to make sure of the time in your location. These days, for any live racing coverage your best bet is to subscribe to TVG, HRTV, or a similar channel on cable or satellite.
Now that the Breeders' Cup is over, there won't be anything on TV until the spring except for the occational movie and what is on TVG, HRTV, and similar channels. Currently I can't even find a movie scheduled. Sorry!
