Since February, Sara Elbadwi, 27, has been working as an on-air handicapper and production assistant/research specialist for the television production team at the New York Racing Association. A native of Red Hook, N.Y., a small upstate town, Elbadwi’s on-desk appearances have taken place on NYRA’s “Talking Horses,” a handicapping show that precedes the day’s racing card. In fact, her first appearance on the show, in January, before she was hired, was part of her job interview.
