On February 26, 1955, Richardson was born in Sac City, Iowa.[1][2] Growing up, Richardson played multiple sports before becoming a runner in his teens.[3] In 1973, Richardson was injured in a car accident and sustained a vertebral compression fracture months before he was to start an athletic scholarship at Drake University.[4] Following his injury, Richardson was advised not to do any running for half a year.[3]
During this time period, Richardson was 20th at the 1979 Boston Marathon and won the 1980 USA Marathon Championships.[12][13] After the championship, it was determined that Richardson and the other competitors had not run the entire race after they were accidentally directed to a road not part of the marathon. With a time of 2:13:54, Richardson qualified for the Boston Marathon and United States Olympic Trials to be held in 1980.[14] That year, Richardson did not complete the Boston Marathon and was 9th in the marathon during the 1980 United States Olympic Trials.[5][15]
In June 1980, Richardson won the Manitoba Marathon with a time of 2:15:15. At Manitoba, Richardson and two other competitors were temporally delayed from finishing the race due to a railway train.[16] Months later, Richardson won the 1980 Chicago Marathon with a new course record time of 2:14:04.[17] Later that year, Richardson finished in 10th at the 1980 New York City Marathon.[18] After competing in the 1981 Nike OTC Marathon, Richardson received a three-month suspension from The Athletics Congress for running in a professional event as an amateur athlete.[19] Throughout the 1980s, Richardson continued to run in marathons until 1985.[1]
