Ever since I found out Miles’ lineage, I’ve been obsessed. There’s been a ton of late-night Google searching and stalking The Blood-Horse and pedigreequery.com to learn everything I can about Miles’ parents and his siblings. I never thought I’d know where he came from, so now that I do, I find it all very fascinating. Even though I don’t know much about Thoroughbred pedigrees, or really Thoroughbred racing in general, here’s what I’ve been able to gather so far.
Miles is by Congaree, a 1998 Chestnut who raced successfully with 25 starts (12-2-4) and won $3,267,490 over his career. Most notably he won the Wood Memorial (G2) and placed 3rd in both the Kentucky Derby (G1) and Preakness Stakes (G1) as a three-year-old. That year  Congaree and Monarchos tied the fastest opening mile in Kentucky Derby history. The following year, Congaree went on to win three G1 Stakes and ran the fastest mile in North America that year during the Cigar Mile, which he won. He continued racing through his 5-year-old year, continuing his winning ways before retiring to Adena Springs Farm in Kentucky, where he stood at stud until 2009. He’s since been moved around a bit and is now standing in New York.
Miles’ grandsire is Arazi, born 1989 in Kentucky and exported to Europe, where he did most of his racing including being named European Horse of the Year in 1991 as well as European and American Champion 2-Year-Old Colt thanks in large part to his victory in the 1991 Breeder’s Cup Juvenile. He stood at stud in no less than five countries (England, United States, Japan, Switzerland and Australia) and has an impressive 9-1-1 record over 14 races, earning $1,213,307.
His sire line traces back to greats such as Blushing Groom, Native Dancer and Nasrullah.
Miles’ dam is Southern Delicacy, a 1997 brown mare who was unraced herself, but by the great Tabasco Cat who won $2,347,671 on the track and stood in the winner’s circle for the 1994 Preakness Stakes and Belmont Stakes, as well as taking second in the Breeder’s Cup Classic, Santa Anita Derby and Travers Stakes. Unfortunately, I’ve not been able to find much on Southern Delicacy — including a picture. Her mother (Miles’ granddam) raced a few times, but was pretty small time, winning only $74k on the track.
The line though does trace back to Storm Cat, Northern Dancer, Native Dancer and Secretariat.
While I’ve recently learned that technically half-siblings with the same sire don’t count as half-siblings [thanks for the education, Carly!] Congaree did sire two G1 winners, but it’s not particularly impressive given the number of offspring running around with Congaree blood.
Unfortunately, Miles doesn’t have any full siblings, but he does have several half-siblings on his dam’s side. Southern Delicacy had a total of five foals, with Miles being the youngest. None of them did well on the track, in fact only two of them ever even placed in the top three at the track. But they all have pretty famous sires: Unbridled’s Song, Grindstone, Silver Charm and Honour and Glory.
Anyways, while Miles may have had some great running blood on top from his sire, his dam line never produced any good racehorses. So to me, it’s really no surprise that Miles didn’t turn out to be much of a racehorse prospect. It looks like most of his other half-siblings have fallen in between the cracks as well, as not much turns up. His most successful sister, Deep South, is a broodmare now it seems but other than that, your guess is as good as mine!
