MyRacehorse Spotlight on Owner Mark Sedran and Featured Runner Sixtythreecaliber

An advertisement that Mark Sedran saw for MyRacehorse inspired him to buy a share in future Kentucky Derby winner Authentic for his wife as a birthday gift. Truth be told, he knew he was going to enjoy it more than his spouse as he has been a racing fan since he was a kid and often went to the races with his dad, who had owned Standardbreds before Mark was born.

Retired now after 31 years in the New York Police Department, where he worked his way up the ranks to become a lieutenant and later a member of the counterterrorism team, that gesture of gifting something unique to his wife was the gateway for Sedran to become very involved as a partner at MyRacehorse (MRH).

With approximately 50 horses in his stable currently, the native New Yorker is having the time of his life and said specifically one of the best parts of the MRH community is meeting fellow owners and enjoying the experience as a group.

“I have seen so many racetracks over the last couple of years and met so many great people,” Sedran said. “When I watched the races with my father as a kid, I was in the stands, as a spectator. You’re always on the other side of the red velvet rope, as a spectator. But MyRacehorse has allowed me, an average blue-collar guy, to get on the other side of the velvet rope and to access places that I never would have been able to before. I mean, horse racing can be a rich man’s sport. But [MyRacehorse] has allowed the average, working person to have a piece of the action and get in the paddock and the winner’s circle. It’s just been a great experience.”

Because he is retired, Sedran, who lives in a suburb north of New York City, eagerly follows his horses to the races when they are running and is a frequent presence at New York Racing Association tracks. He has also attended several exclusive events that MyRacehorse regularly presents as perks for its partners at tracks around the country.

One of the many thrills that Sedran has experienced occurred just recently, when Sixtythreecaliber (a MyRacehorse featured horse, see below) became a graded stakes winner at Aqueduct in the $175,000 Comely Stakes the day after Thanksgiving. The filly, who has now won 5 of 7 career starts, was an 11-1 longshot in the Grade 3 Comely and Sedran accepted the trophy, joined by other MRH partners, in the winner’s circle.

“It’s even better when they go off a longshot because it’s unexpected,” Sedran said. “Really with Sixtythreecaliber, I was just hoping she would place and that would increase her value down the line as a broodmare. That she ended up winning was pretty awesome.”

Mark Sedran’s passion and support help make MyRacehorse an amazing venture into racehorse ownership, and you can be sure there will be many more unforgettable moments on his MRH journey.

Graded stakes winner Sixtythreecaliber is on target to make her 4-year-old debut in the Grade 3, $300,000 Houston Ladies Classic Stakes on Jan. 28 at Sam Houston Race Park.

A Tom Amoss-trained filly, Sixtythreecaliber is a winner of five of seven starts, including the Grade 3 Comely Stakes at Aqueduct in November, which was her third consecutive victory and her second straight stakes win.

Purchased by MyRacehorse and Spendthrift Farm at the 2020 Keeneland September yearling sale for $250,000, Sixtythreecaliber has earned $269,532 to date while winning races at Aqueduct, Churchill Downs, and Horseshoe Indianapolis.

Sixtythreecaliber is from the first crop of rising star stallion Gun Runner, who was the leading freshman sire in 2021 and the leading second-crop sire of 2022. Sixtythreecaliber ranks among Gun Runner’s top 10 lifetime leading progeny in money earned. She is a half-sister to Grade 3 stakes winner Gunmetal Gray, the winner of the 2019 Sham Stakes.

Tom Amoss is seeking to win the Houston Ladies Classic Stakes for the first time, after a narrow defeat with odds-on Serengeti Empress (the 2019 Kentucky Oaks winner) when she finished second in 2020. Later that year, Serengeti Empress went on to win the Grade 1 Ballerina Stakes at Saratoga and ran second in the Breeders’ Filly and Mare Sprint.

MyRacehorse finished third in the 2020 Houston Ladies Classic Stakes with Street Band.
