Letruska is a bay mare who was bred in Kentucky by St George Stables, owned by Mexican billionaire Germán Larrea Mota-Velasco.
[4] Letruska's dam, Magic Appeal, is the full sister to Grade I winner J P's Gusto and is from the family of champion Proud Spell.
[7] Letruska suffered her first loss in the Tropical Park Oaks on December 28 over a turf course labeled as good.
[6] Letruska began her four-year-old campaign on April 16, 2020, at Oaklawn Park with a front-running win in an allowance race at odds of 3–1.
[11] On August 8, Letruska shipped to Saratoga for her first start at the Grade I level in the Ballerina Stakes, run at a sprint distance of seven furlongs.
Letruska was the fourth betting choice at odds of 5–1 in a field of seven that included multiple stakes winners Bellafina, Serengeti Empress and Come Dancing.
Letruska tracked the fast early pace set by Serengeti Empress but tired to finish fifth.
She went to the early lead and set a brisk opening pace of :46.20 for the half-mile, then held off the closing drive of Royal Flag to win by a length.
[15] "I had a big question mark about today, because after her last race in New York, I decided to remove the blinkers", said Gutierrez.
"[17] On March 13, Letruska entered the Azeri Stakes at Oaklawn Park where she went off as the slight favorite over Shedaresthedevil, who had won the Kentucky Oaks at age three.
Letruska broke a bit slowly then moved up to press the pace while being carried three wide around the turns.
Turning into the stretch, Swiss Skydiver started to drop back while Monomoy Girl moved closer to Letruska.
The two mares dueled down the stretch, with Monomoy Girl getting her head in front with a furlong remaining.
[20] Gutierrez had instructed jockey Irad Ortiz Jr. that even if Letruska broke poorly, he should get in front and "make the others think".
[25] The win established her position at the top of the older female division and had Gutierrez considering a race against male horses.
[26] After the win, Letruska moved to the head of the NTRA Top Thoroughbred Poll that ranks North American racehorses in training.
[27] She was later passed by Knicks Go after he won the Whitney Stakes in early August, but remained the clear leader in the female division.
[28] Letruska was given a brief layoff then returned in the Personal Ensign Stakes at Saratoga on August 28 as the odds-on favorite in a field of nine.
She ran a fast opening quarter mile in 23.01 seconds to get the early lead, pressed by Miss Marissa, Swiss Skydiver and Harvey's Lil Goil.
After completing the half in 46.74 and three-quarters in 1:10, her early rivals began to tire, eventually finishing well back.
Letruska then held off the closing kick of longshots Bonny South, Royal Flag and Dunbar Road to win by half a length.
[33] Letruska made the first start of her six-year-old campaign on February 26, 2022 in the Royal Delta Stakes at Gulfstream.
Letruska broke out and was a bit rank, but quickly straightened to show the way past the wire the first time.
Shaken up when straightened for home, she drifted down the stretch, but held late under continued steady handling to defeat Clairiere by 1+1⁄4 lengths in a time of 1:42.22.
[20] On June 11, Letruska faced Clairiere and Malathaat in the Grade I Ogden Phipps Stakes at Belmont Park, an event she had won the previous season.
[35] On August 27 in the Grade I Personal Ensign Stakes, Letruska was made the 12/5 second favorite in a small field of five which included rivals Malathaat and Clairiere.
Letruska once again went to the lead but with three-sixteenths of a mile to run she was headed and ended up in third place behind Malathaat and Search Results.
[36] On October 9, Letruska finished fourth in Keeneland's Spinster Stakes to Malathaat, beaten by 16+3⁄4 lengths.
