Thursday is the deadline to register to buy 2014 Kentucky Derby and Oaks tickets online, Churchill Downs said. Go to Kentuckyderby.com or Churchilldowns.com and click on "2014 Ticket Request" to register.
Seats go on sale online in November, when registrants will be advised via email on a date and start time for ticket sales.
Registered fans will have a first-come, first-served opportunity to buy two-day packages of Derby and Oaks seating in locations throughout the track.
About 19,000 of more than 55,000 reserved seats at the 2013 Derby and Oaks were bought through the online sale, Churchill said.
There is a limit of six tickets per household.
According to the track, it refunded more than $1 million in purchases last year from buyers who were found to have violated the track's ticketing policy to sell them to brokers or on the secondary market.
