Lane Frost (October 12, 1963 in La Junta, Colorado – July 30, 1989 in Cheyenne, Wyoming) was a professional bull rider and Professional Rodeo Cowboy Association member, who died as a result of injuries sustained in the arena at the 1989 Cheyenne Frontier Days Rodeo seconds after he dismounted his bull "Taking Care of Business," and was later taken off the riding circuit.
Frost was born in La Junta, Colorado, the son of Clyde and Elsie Frost. He spent his childhood in Vernal, Utah, and his teenage years in Lane, Oklahoma. He showed an interest in rodeo at the age of three, and began riding calves when he was ten. He was taught the art of riding by his father and also his good friend Freckles Brown, who was a World Champion Bull Rider. In Oklahoma, he was the National High School Bull Riding Champion in 1981. Frost was the Bull Riding Champion of the first Youth National Finals held in Fort Worth, Texas, held in 1982. On January 5, 1985, he married Kellie Kyle, a barrel racer from Quanah, Texas.
Frost joined the Professional Rodeo Cowboys Association (PRCA) and began rodeoing full time after graduating from high school in 1982. In 1987, he realized a lifelong dream when he became the PRCA World Champion Bull Rider at the age of 24. That same year, the great bull "Red Rock," owned by Growney Bros. Rodeo Company, was voted Bucking Bull of the Year. In 309 attempts, no one had ever ridden "Red Rock," and in 1988, at the Challenge of Champions, Frost rode "Red Rock" in seven exhibition matches and was successful in four out of seven tries. Frost went on to compete at the Winter Olympics in Calgary, Alberta, Canada. This was the first time that an exhibition rodeo was held at the Olympics.
