Q: Passage: Denean Howard and her 3 sisters gained fame in 1979 when the four of them teamed up to set the National High School record in the 4x440 yard relay for San Gorgonio High School in San Bernardino. That distance is now rarely run as the NFHS converted to metric distances, so the record still stands today. Later teams with Denean broke the record for the slightly shorter 4x400 metres relay, after sister Atra graduated and the rest of the family moved to Kennedy High School (Los Angeles). Denean was the California High School Athlete of the Year at Kennedy in 1982, following in the footsteps of her sister Sherri. Also following her sister, she was named the national Girl's "High School Athlete of the Year" by Track and Field News, two years in a row. Her 1982 52.39 was the NFHS national high school record for eighteen years, before it was beaten by Monique Henderson. At age 15, she qualified for the ill-fated 1980 U.S. Olympic Team which was part of the 1980 Olympic Boycott finishing behind sister Sherri at the 1980 Olympic Trials, the first sisters to make the Olympic team simultaneously in the same event.
