Career.
Gray was born in Gallatin, Tennessee, and grew up on a farm around horses and mules. He first began training horses as a side job while working for a livestock transportation company, and in 1967 attended the Tennessee Walking Horse National Celebration when Doug Wolaver won the World Grand Championship on Go Boy's Sundust. On the ride home, Gray told his wife he would like to ride in the World Grand Championship someday. She told him, "You have lost your everlasting mind". Gray contacted notable horse trainer Sam Paschal, who found him a job as a trainer.
Gray ran a training stable in Lewisburg, Tennessee, during the 1970s. 
In 1972, Gray and the horse Delight Bumin Around won the Reserve World Grand Championship at the Tennessee Walking Horse National Celebration. Gray was also named Horseman of the Year. At the Celebration the following year, the pair won the World Grand Championship, beating 14 other horses and riders to do so.
Gray competed in the Celebration consistently, and in 1975 won the Two-Year-Old World Championship with Powerful Delight. Gray won a second World Grand Championship in 1982 with the horse Pride's Secret Threat.

Gray trained He's Puttin' on the Ritz, who won the Three-Year-Old World Championship in 1994, before changing trainers and winning a World Grand Championship. 
In 2010, 26 years after his third win, Gray rode the chestnut stallion The Coach to a World Grand Championship.
