The TwinSpires promo runs for 30 days and 1/ST BET's promotion runs for 60, while the FanDuel Racing promo runs until June 28 and is available on specific race days.

Bonus bets are typically awarded within 72 hours, and once they are available, credits expire within seven days. Horse racing promos are available to users physically located in states where the racebook is legal, and users must be 21 or older, though the age requirement in some states is 18.
