The Kentucky Derby 2025 takes place on Saturday at Churchill Downs, and you'll find differing opinions on how often a horse should race leading up to it. Most trainers have seemed to settle in between four and eight starts,

Notable: McPeek last year became the first trainer to win the Kentucky Oaks (with Thorpedo Anna) and the Kentucky Derby (with Mystik Dan) since Ben Jones in 1952. His horse in this year’s Oaks is the No. 10, Take Charge Milady, who opened at 12-1.
