Kentucky Derby 2015: Who is bred for the distance?

Keen Ice, shown training at Churchill on April 25, was the only member of the Derby field to have both his sire and dam rank in the top four by average winning distance.

This year’s Kentucky Derby might be quite polarizing between the favorites and the longshots, but the great equalizer for them all will be the distance of the race.

The Derby will be the first start at 1 1/4 miles for every horse in the field, and many of the horses running Saturday will never run 10 furlongs in competition again, leaving bettors to speculate on each horse’s capability at the classic distance.

Since there is no prior ontrack performance on which to base an opinion, one helpful tool to measure a horse’s capability is the average winning distance (AWD) of the sire’s and dam’s progeny.

While there are always exceptions, the AWD numbers can provide a snapshot of a sire’s ability to impart stamina on his progeny or a dam’s abilities as a producer. For example, if a stallion’s AWD is 7.75 furlongs, then the average distance of a race won by one of his offspring is between 7 1/2 furlongs and one mile. A foal by that sire should be more likely to handle a route of ground than one by a sire with a lower AWD number.

Examining AWDs does not promise to identify the winner at the top of the charts, but it can help identify longer-priced horses who are capable of filling out the exotics based on their ingrained stamina. Over the past two years, horses who have made noise at a price in Triple Crown races after finishing at or near the top of the AWD figures include 2013 Derby runner-up Golden Soul at 35-1, 2013 Preakness Stakes winner Oxbow at 15-1, and 2014 Belmont Stakes runner-up Commissioner at 28-1.

Taking into account the comparative AWDs from the sires and dams of this year’s Kentucky Derby entrants, longshot Keen Ice emerges as the horse who appears best equipped to handle the distance from a pedigree standpoint.

Keen Ice, owned by Donegal Racing and bred in Kentucky by Glencrest Farm, was the only member of the Derby field to have both his sire and dam rank in the top four by AWD.

His sire, two-time Horse of the Year Curlin, established his distance credentials early at stud, siring Belmont Stakes winner Palace Malice in his first crop and Preakness Stakes runner-up Ride On Curlin with his next group of foals. Curlin’s AWD of 7.56 furlongs ranked him fourth among the 20 Derby sires, and he is the only sire in the top five with fewer than five crops of racing age.

Keen Ice is the first runner out of the unplaced Awesome Again mare Medomak, who ranked fourth out of the 22 Derby broodmares with an AWD of eight furlongs based on Keen Ice’s maiden victory at Churchill Downs. The sample size is admittedly small compared with more experienced broodmares, but graduating at a non-sprint distance is a feat to which 14 of the 22 Derby hopefuls cannot lay claim.

Wood Memorial winner Frosted and Blue Grass Stakes runner-up Danzig Moon tied for the second-highest combined rank among the Derby entrants. Danzig Moon is the less decorated of the two, but his dam outranks all other Derby broodmares with an AWD of 8.90 furlongs.

Leaveminthedust, a placed Danzig mare, has had four winners from as many runners, including Global Express, a winner at 1 3/8 miles and 1 1/2 miles over the turf. Danzig Moon is a winner at a mile, while half-sibling Horseshoe Hill contributed a victory at 1 1/16 miles. The only foal out of Leaveminthedust without a win at a mile or longer was Back in a Flash, who won once at five furlongs.

Also of note, Danzig Moon’s sire, Malibu Moon, is the only stallion represented in this year’s field to have sired a Derby winner: Orb in 2013. However, Malibu Moon is tied for ninth among the Derby sires with an AWD of 7.06 furlongs.

Tied for the field’s top stallion with an AWD of 8.52 furlongs are Giant’s Causeway, the sire of multiple Grade 1 winner Carpe Diem, and Dubawi, the sire of UAE Derby winner Mubtaahij.

Five first-crop sires are represented in this year’s Derby, meaning their AWD numbers could fluctuate as more of their foals mature and compete in longer races.

That makes the output of Temple City, the sire of Bolo, especially interesting. The son of Dynaformer’s foals are winning at an average distance of 7.21 furlongs, tying him for seventh among the Derby sires and putting him well ahead of the next-closest first-timer, Warrior’s Reward, the sire of Tencendur, in 13th at 6.76 furlongs.
