Thousands of horse racing fans are expected at Del Mar Racetrack as the two-day Breeders' Cup World Championships kick off Friday, with the first day's events highlighting the potential future stars of the sport. It marks the third time that one of horse racing's most prestigious annual series of races has been hosted by Del Mar, which also hosted the Breeders' Cup in 2017 and 2021 and has already been chosen as the site for next year's event. "Our return to Del Mar in back-to-back years marks the continuation of a wonderful collaboration and successful partnership, both with our friends at the track and with the greater San Diego area, demonstrating our continued commitment to California horse racing," Drew Fleming, president and CEO of Breeders' Cup Ltd, said after Del Mar was chosen to host the 2025 Breeders' Cup. Attendance at Del Mar will be capped at 37,500 for each of the two days of the Breeders' Cup.
