2018 Triple-Crown winner Justify has one son in the field, American Promise, trained by D. Wayne Lukas. According to Brooks Holton of the Louisville Courier Journal, this will mark the first time the offspring of two Triple-Crown winners have been in the same Kentucky Derby field since 1952.

A pre-race tradition is the walkover, when the horses are led from the stables to the paddock where they are saddled for the race. Some are cool and calm, others get fractious and sweaty. They walk on the track along the rail with fans yelling all the way. The riders emerge from the jockeys’ room and walk to the paddock to meet their mounts.
