2009: two-year-old season

Blind Luck won four of her six career juvenile starts. Two of her wins were in Grade I stakes races: the Oak Leaf Stakes and the Hollywood Starlet Stakes. She also placed third in the Grade I Breeders' Cup Juvenile Fillies behind Shebewild and second in the Grade I Del Mar Debutante Stakes to Mi Sueno.

2010: three-year-old season

Blind Luck made her 3-year-old debut a winning one in the Grade I Las Virgenes Stakes where she rallied to win by a nose over Evening Jewel. In the Grade I, $250,000 Santa Anita Oaks, Blind Luck closed well but found herself trapped on the inside until the final sixteenth of a mile. She rallied late but fell short by 3/4 lengths, coming in third behind Crisp and All Due Respect. In the Grade II Fantasy Stakes at Oaklawn Park on April 3, she won as a come-from-behind favorite, taking the race by 2½ lengths. The 136th running of the Grade I Kentucky Oaks took place on April 30, 2010, on Churchill Downs' traditional dirt course. Blind Luck was listed as a 6-5 morning-line favorite in a field of 14 and broke from post 5 with regular jockey Rafael Bejarano aboard. After checking in last for the first half of the race, she came home strongly to catch Evening Jewel at the wire to win the Oaks. Her time for the 1 1/8-mile race was 1:50.70.

Blind Luck returned to racing in the first week in June in the Grade II Hollywood Oaks. There she lost by 1½ lengths to Switch when unable to catch that rival in the stretch. Blind Luck then shipped into Delaware Park for the Grade II Delaware Oaks, which she won by a nose over Havre de Grace in late-running fashion. She remained undefeated on dirt and won over a sloppy track. In the Grade I, 1+1⁄4-mile Alabama Stakes at Saratoga on August 21, a showdown between Blind Luck and the odds-on choice, Devil May Care, believed to be the best 3-year-old filly on the East Coast, never materialized as Devil May Care finished 4th. Instead Blind Luck ran down Havre de Grace, her foe from the Delaware Oaks, to win by a neck.

On October 2, Blind Luck faced Havre de Grace again in the Grade II Cotillion Stakes at Parx. Second choice Havre de Grace held off Blind Luck by a neck. Blind Luck took on older fillies and mares for the first time in the Grade I Breeders' Cup Ladies Classic at Churchill Downs. Racing under lights for the first time, she settled in 10th position in the 11-horse field. Forced to chase a slow pace, Blind Luck released her customary rally only to come up 13⁄4 lengths short of 4-year-old filly Unrivaled Belle, while Havre de Grace was 3rd.

2011: four-year-old season

In her 4 year old debut, Blind Luck started in the Grade II El Encino Stakes at Santa Anita Park, finishing second to Always a Princess. Blind Luck again finished second to Always a Princess in the Grade II La Cañada Stakes at Santa Anita Park. On March 19, Blind Luck renewed her rivalry with Havre De Grace in the Grade III Azeri Stakes at Oaklawn Park. This time Havre De Grace won, leaving their race record against each other as Blind Luck with two wins and Havre De Grace with two. (Blind Luck also finished second to Havre De Grace's third in the 2010 Breeders' Cup Ladies Classic). Blind Luck's connections opted to skip the Grade I Apple Blossom Handicap, which Havre De Grace won over California filly Switch. Snapping a five-race losing streak, on May 6, Blind Luck took the Grade II La Troienne Stakes at Churchill Downs, catching 2010 Breeders' Cup Ladies Classic winner and reigning American Champion Older Female Unrivaled Belle in the final strides after stumbling badly at the start. Rallying from last, Blink Luck won her 6th career Grade I in the Vanity Handicap at Hollywood Park. Blind Luck won the Delaware Handicap by a nose over her archrival Havre de Grace after a lengthy stretch duel. This put their race record at 3 wins for Blind Luck and 2 for Havre de Grace. Life at Ten, 2010's Delaware Handicap winner, finished 181⁄2 lengths further back in third.

Blind Luck returned to the races on Saturday, October 1 in the Lady's Secret Stakes at Santa Anita's autumn meeting. After breaking slowly as usual, she dropped far behind and lost contact with the field on the second turn. She finished an uncharacteristic last place in the field of seven fillies and mares, the first time in her career she had been worse than third. This poor performance rendered her out of the Breeders' Cup. Tests and scans taken on her reportedly revealed that nothing was physically wrong.
