L and N Racing LLC and Winchell Thoroughbreds LLC

Joan Winchell and her son, Ron, are partners in Winchell Thoroughbreds, continuing the family's prominent racing and breeding operation started by the late Verne Winchell, Joan's husband and Ron's father. Verne Winchell, who died in 2002 at the age of 87, founded the doughnut company Winchell's and later was the CEO and chairman of the Denny's restaurant chain.

The Winchells also raced Tapit, now a leading sire, in partnership. Winchell Thoroughbreds bred and raced Breeders' Cup Distaff winner Untapable who was later named champion 3-year-old filly, as well as multiple graded stakes winner Tapiture, who now stands at stud at Darby Dan Farm. In 2017, Gun Runner capped a Horse of the Year campaign with a win in the Breeders' Cup Classic for Winchell Thoroughbreds and partner Three Chimneys Farm.

L and N Racing is a four-way partnership comprised of Tulsa, Okla. lawyer Lee Levinson; his sons Andy and Michael; and family friend and prosecutor Don Nelson.

In 2021, L and N Racing and Winchell Thoroughbreds partnership won their first Breeders’ Cup race when unbeaten Echo Zulu, a daughter of Gun Runner, romped in the Juvenile Fillies at Del Mar.
