The first full weekend in October is traditionally one of the busiest and most important in North American Thoroughbred racing, as the final round of “Win and You’re In” qualifying races in North America that offer spots in the Breeders’ Cup World Championships are held at various racetracks.

Several of them anchor what’s become a destination event in the sport each autumn: Keeneland’s Fall Stars Weekend. The three-day span, which kicks off on the Lexington, Ky., track’s opening Friday and ends Sunday, features a bevy of graded stakes races that are held in front of upwards of 20,000 spectators on average each day.

This year, eight Keeneland stakes are Challenge Series “Win and You’re In” races. The winner of each race receives an automatic berth to a corresponding Breeders’ Cup event, with entry fees waived and travel expenses provided. The 41^st annual Breeders’ Cup is set for Nov. 1-2 at Del Mar in Southern California.

Two other stakes races at Keeneland discussed below are not official Challenge Series qualifiers but still have been influential in Breeders’ Cup history. Enjoy this preview of Fall Stars Weekend, where you just might see one, two, or more horses visit the winner’s circle at the picturesque central Kentucky track and then achieve even greater glory four weeks later at the Breeders’ Cup.

Coolmore Turf Mile Stakes

When: Saturday, Oct. 5

How to watch: NBC and Peacock/FanDuel TV

“Win and You’re In” for: FanDuel Breeders’ Cup Mile Presented by Permanently Disabled Jockeys Fund

Why it’s important: This race, first held in 1986, has been a key prep for the Breeders’ Cup Mile from the outset. Only two horses have won the Turf Mile and BC Mile in the same year, but many other Turf Mile also-rans have made an impression, including Opening Verse, Miesque’s Approval, and Master of The Seas, who finished second, fourth, and second, respectively, in the Turf Mile in 1991, 2006, and 2023 before winning the BC Mile weeks later.

Best winner during the Breeders’ Cup era: Steinlen (1989) and Wise Dan (2012) are the only two Turf Mile winners to take the Breeders’ Cup Mile later in the same year, while Court Vision won both races in different years (Turf Mile in 2009 and the BC Mile in a huge upset in 2011). Wise Dan takes top honors among that trio as he also finished second in the 2013 Turf Mile at Keeneland prior to posting repeat win in the BC Mile. He then won another Turf Mile in 2014. His runner-up finish in 2013 Turf Mile came when the race was moved to the all-weather main track due to rain. Wise Dan missed a three-peat bid in the Breeders’ Cup Mile in 2014 due to an ankle injury, and the Turf Mile at Keeneland turned out to be the final start of a sensational career. He entered the Racing Hall of Fame in 2020.

Last year’s results:  A thrilling stretch run highlighted the 2023 Turf Mile, resulting in Repole Stable and St. Elias Stable’s Up to the Mark narrowly edging favored Master of The Seas to prevail by a nose. Up to the Mark went to the Longines Breeders’ Cup Turf rather than the FanDuel BC Mile at Santa Anita Park, and he ran lights out when extended to a mile and a half, finishing second to Auguste Rodin. Master of The Seas, meanwhile, rallied like a freight train in the BC Mile, closing to win by a nose over stablemate Mawj.

2024 field: A strong nine-horse field is lined up for Saturday’s Coolmore Turf Mile, headlined by Chad Brown-trained Carl Spackler, who enters on a two-race winning streak, both earned in Saratoga stakes.

Juddmonte Spinster Stakes

When: Sunday, Oct. 6

How to watch: CNBC and Peacock/FanDuel TV

“Win and You’re In” for: Longines Breeders’ Cup Distaff

Why it’s important: This race, which dates back to 1956, has commingled with the Breeders’ Cup from year one of the World Championships in 1984, when Princess Rooney followed up a six-length romp in the Spinster with a seven-length blowout in the inaugural Distaff at Hollywood Park. Since then, six more fillies/mares have won both races in the same year – and one of them pulled that feat off back-to-back.

Best winner during the Breeders’ Cup era: The seven Spinster-Distaff dual winners are an impressive group, indeed. After Princess Rooney, you’ve got Sacahuista (1986), Bayakoa (1989, 1990), Inside Information (1995), Blue Prize (2019), Malathaat (2022), and Idiomatic (2023). Princess Rooney, Bayakoa, and Inside Information are all in the Racing Hall of Fame, and Malathaat has a good chance to receive an invitation in the years to come. Bayakoa’s four wins at the turn of the 20^th century’s final decade give her the edge here. Janis and Frank Whitham’s mare won those races by a combined 22 ¾ lengths. Naturally, Bayakoa was voted champion older female at the Eclipse Awards for both years, and entered the Hall of Fame in 1998.

Last year’s results: Entering on a three-race winning streak, all in stakes, Juddmonte’s Idiomatic was far too tough for the opposition in the Spinster, taking command early and rolling to a 4 ¼-lengh win. That made her a 9-5 post-time favorite in the Longines Distaff against a tougher field, but she validated those odds by posting a half-length win over Randomized.

2024 field: Guess who’s back? Idiomatic returns for a repeat bid in the Juddmonte Spinster and figures to be a heavy favorite when the gate opens facing five other fillies and mares. She enters off of a good runner-up finish in the Personal Ensign Stakes at Saratoga, where she lost by a head to Raging Sea after opening up on the field in early stretch.

Claiborne Breeders’ Futurity

When: Saturday, Oct. 6

How to watch: NBC and Peacock/FanDuel TV

“Win and You’re In” for: FanDuel Breeders’ Cup Juvenile Presented by Thoroughbred Aftercare Alliance

Essential Quality (Eclipse Sportswire)

Why it’s important: As with the Spinster, this Keeneland Fall Stars race has had significant crossover with the Breeders’ Cup since the 1980s. Six 2-year-olds have won both events in the same year: Tasso (1985), Boston Harbor (1996), Favorite Trick (1997), Classic Empire (2016), Essential Quality (2020), and Forte (2022). Last year’s winner, Locked, ran third to Fierceness in the FanDuel Juvenile Presented by TAA.

Best winner during the Breeders’ Cup era: Favorite Trick won all eight of his starts at age 2 for owner Joseph LaCombe, trainer Patrick Byrne, and regular jockey Pat Day. After wrapping up the season with a 5 ½-length rout in the Breeders’ Cup Juvenile, the Phone Trick colt received an Eclipse Award as Horse of the Year along with a champion 2-year-old male trophy. Favorite Trick would go on to have more success at age 3, winning the Jim Dandy and two other graded stakes (including the Turf Mile discussed above), but he’ll be remembered for his superlative juvenile campaign, one of the best debuts in recent racing history.

2024 field: A competitive group of juveniles are lined up for this year’s Breeders’ Futurity, including Hopeful Stakes runner-up Ferocious, dominant Ellis Park maiden winner East Avenue, and Saratoga maiden winners Filoso and Dapper Moon.

Darley Alcibiades Stakes

When: Friday, Oct. 4

How to watch: FanDuel TV

“Win and You’re In” for: NetJets Breeders’ Cup Juvenile Fillies

British Idiom (Eclipse Sportswire)

Why it’s important: The premier race for 2-year-old fillies at Keeneland has had an impact on the Breeders’ Cup Juvenile Fillies similar to the Breeders’ Futurity for males. Five fillies have won both races in the same calendar year: Eliza (1992), Countess Diana (1997), Silverbulletday (1998), British Idiom (2019), and Wonder Wheel (2022). Another notable filly, Stephanie’s Kitten, won the Alcibiades in 2011 when the race was contested on an all-weather track and then used that as a springboard to victory in the Breeders’ Cup Juvenile Fillies Turf. As with the Claiborne Futurity, last year’s Alcibiades winner, Candied, went on to finish third in the NetJets Juvenile Fillies.

Best winner during the Breeders’ Cup era: Silverbulletday, owned by Mike Pegram and trained by Bob Baffert, won her first three races in 1997 but tired in the Del Mar Debutante to finish fourth. The daughter of Silver Deputy shipped from California to Keeneland and stretched out for the 1 1/16-mile Alcibiades, and that turned on the switch, as she rolled by 2 ½ lengths and launched an eight-race winning streak that included the Juvenile Fillies in her next start, the Kentucky Oaks in 1999, and five other graded stakes. In fact, after the streak ended with a seventh-place finish in the 1999 Belmont Stakes, Silverbulletday won three more graded stakes during her sophomore season. She secured Eclipse Awards in 1998 and 1999 and joined the Hall of Fame in 2009.

2024 field: The top three finishers in Saratoga’s Spinaway Stakes – Immersive, Quietside, and Sherbini – headline Friday’s race.

Stoll Keenon Ogden Phoenix Stakes

When: Friday, Oct. 4

How to watch: FanDuel TV

“Win and You’re In” for: Breeders’ Cup Sprint

Champion Runhappy in 2015. (Eclipse Sportswire)

Why it’s important: The Phoenix is the oldest recognized race in North America and dates back to 1831. It was added as a “Win and You’re In” race for the Breeders’ Cup in 2012, and soon after its stature rose as a prep, as both 2014 and 2015 winners Work All Week and Runhappy trained on to capture the BC Sprint.

Best winner during the Breeders’ Cup era: Runhappy certainly deserves mention based on a brilliant 2015 campaign where he won six out of seven starts including the Phoenix and BC Sprint (which was held at Keeneland), but the best Phoenix winner in terms of overall Breeders’ Cup accomplishments is Whitmore. That fan favorite gelding ran in four consecutive editions of the Phoenix Stakes and four Breeders’ Cup Sprints as well from 2017 to 2020. He won the Phoenix in his first try, and then finished second (by a head), second again, and fourth in his final appearance in 2020, when he was 7 years old. The Ron Moquett trainee then targeted the Breeders’ Cup Sprint for a fourth time after finishing eighth, second, and third in his first three starts. With Irad Ortiz Jr. aboard, Whitmore saved ground into the stretch, moved out and found a seam, and charged to score by 3 ¼ lengths at odds of 18.40-1, providing his owners and fans with one of the highlights of an exciting 2020 Breeders’ Cup held at Keeneland during the height of the COVID-19 pandemic. Whitmore retired in 2021 with 15 wins, 13 seconds, and 5 thirds in 43 career starts and more than $4.5 million in earnings.

2024 field: Friday’s race is led by Nakatomi, who finished second in the 2023 Phoenix and third in the BC Sprint, and 2022 Phoenix winner Manny Wah.

Thoroughbred Club of America Stakes

When: Saturday, Oct. 5

How to watch: NBC and Peacock/FanDuel TV

“Win and You’re In” for: PNC Bank Breeders’ Cup Filly & Mare Sprint

Why it’s important: This seven-furlong race sent winners to take the Breeders’ Cup Filly & Mare Sprint in 2009 (Informed Decision), 2010 (Dubai Majesty), and 2012 (see below). Yuugiri, winner of the 2023 TCA Stakes, checked in second behind champion Goodnight Olive in last year’s PNC Bank BC F&M Sprint at Santa Anita.

Best winner during the Breeders’ Cup era: The pride of Frankfort, Ky., Groupie Doll emerged as a champion after trainer Buff Bradley shortened her up in distance during spring 2012. She was at her best that fall, winning the TCA Stakes by 6 ½ lengths on Keeneland’s all-weather surface and then romping in the Filly & Mare Sprint on dirt at Santa Anita Park by 4 ½ lengths. One year later, the daughter of Bowman’s Band was slightly less dominant but still elite, and she followed up a third-place finish in the TCA to Judy the Beauty by turning the tables on that foe in the Filly & Mare Sprint, which was held again at Santa Anita. Groupie Doll was voted champion female sprinter for both 2012 and ’13. Judy the Beauty, meanwhile, won the Breeders’ Cup Filly & Mare Sprint in 2014 and was honored with an Eclipse Award as champion female sprinter for that year.

2024 field: A competitive field lacking a clear standout includes Brightwork, a multiple graded stakes winner in 2023 who won her first start of the year Aug. 31 at Saratoga, and a pair of Steve Asmussen trainees, stakes winners Clearly Unhinged and Zeitlos.

Jessamine Stakes Presented by Keeneland Sales and Castle & Key Bourbon Stakes

When: Friday, Oct. 4 (Jessamine) and Sunday, Oct. 6 (Bourbon)

How to watch: FanDuel TV (Jessamine) and CNBC and Peacock/FanDuel TV (Bourbon)

“Win and You’re In” for: John Deere Breeders’ Cup Juvenile Fillies Turf (Jessamine) and Breeders’ Cup Juvenile Turf (Bourbon)

Rushing Fall (Eclipse Sportswire)

Why they’re important: These two races for juvenile fillies (Jessamine) and males (Bourbon) are usually loaded with promising Breeders’ Cup prospects that are coming off of maiden or allowance wins. To date, two fillies have managed to win both the Jessamine and Juvenile Fillies Turf and no Bourbon winner has won the Juvenile Turf. There’s an asterisk involved with the latter record, however, as Tiz the Bomb, who took the 2019 Bourbon by three-quarters of a length, then finished second by 1 ½ lengths to European star Modern Games in the Juvenile Turf at Del Mar but paid out as the winner in parimutuel pools. That memorable occurrence, which upsets many horseplayers to this day, came after Modern Games was designated to run for purse money only by stewards due to a gate incident right before the start.

Best winner during the Breeders’ Cup era: The two Jessamine winners who trained on to shine at the Breeders’ Cup are Rushing Fall (2017) and Aunt Pearl (2020). Rushing Fall was simply one of the best turf females of the 2010s, winning 11 of 15 starts for owner e Five Racing Thoroughbreds, trainer Chad Brown, and jockey Javier Castellano for earnings of nearly $2.89 million. Her win in the Jessamine came in her second career start, and the More Than Ready filly followed that up with a three-quarter-length score in the Juvenile Fillies at Del Mar. Over the next 2 ½ years, she won eight more graded stakes, including five Grade 1s, and finished up with a neck loss to European filly Audarya in the 2020 Maker’s Mark Breeders’ Cup Filly and Mare Turf. Rushing Fall won five graded stakes at Keeneland in her career, second only to Wise Dan’s seven in the storied track’s history.

Other races:

The First Lady Stakes Presented by UK HealthCare was removed from the Breeders’ Cup Challenge Series in 2022 after formerly serving as a “Win and You’re In” qualifier for the Maker’s Mark Breeders’ Cup Filly & Mare Turf. The First Lady was first held in 1998 and the BC Filly and Mare Turf a year later, and since then there’s been consistent crossover. Three fillies/mares have won both races in the same year: Intercontinental in 2005 (upsetting the great Ouija Board in the Filly and Mare Turf), Forever Together in 2008, and Dayatthespa in 2014. In addition, two First Lady winners trained on to win the Breeders’ Cup Mile competing against males: Hall of Famer Tepin in 2015 and Uni in 2019. Last year’s First Lady winner, Gina Romantica, ran in the FanDuel BC Mile Presented by PDJF and finished fourth; she’s back for a repeat bid Saturday.

Also on Saturday, the Woodford Stakes Presented by FanDuel, a 5 ½-furlong turf dash, has sent several entrants on to good showings in the Prevagen Breeders’ Cup Turf Sprint in recent years, the best being Golden Pal. The Wesley Ward trainee is the only horse to date to win both the Woodford and the BC Turf Sprint in the same year, which occurred in 2021. Golden Pal also won the Woodford in 2022 but could not overcome a bad start in the Breeders’ Cup Turf Sprint back at Keeneland, finishing 10^th as the favorite. Nobals, upset winner of the BC Turf Sprint in 2023, is entered in a full field for Saturday’s renewal.
