The deadline for trainers to register for this year's Claiming Crown is Aug. 31, Gulfstream Park officials said.
The nomination structure was changed this year. As reported earlier, trainers now can nominate themselves and be eligible to nominate horses at the regular time of nomination. Trainers that don't pay the $100 fee by Aug. 31 can only nominate horses through the supplemental process.
Eligible trainers may nominate horses to Claiming Crown races on or before Nov. 9. In a change from prior years, the horse and Claiming Crown race must be named at the time of nomination.
Supplemental nominations and entries will be taken Nov. 28.
"The Claiming Crown is a great day of racing for the blue-collar horses of our sport," Gulfstream racing secretary Dan Bork said. "Trainers do not want to miss out on being eligible for this big event on opening day at Gulfstream Park."
The 14th edition of the Claiming Crown, a project of the Thoroughbred Owners and Breeders Association and National Horsemen's Benevolent and Protective Association, will be the richest ever with seven races worth a combined $850,000.
Four races will have purses of $100,000, two at $125,000, and the Jewel at $200,000.
