While running for Pasadena High School, Sanford won the 400 metres, anchored his team to victory in the 4x400 metres relay and was second in the 200 metres at the 1977 CIF California State Meet. After high school, he moved on to the University of Southern California. Here he enjoyed great track success over the next four years. Sanford still holds the school records in the 100 metres and 200 metres - a statement all the more impressive considering some of the people who have been through the program including Olympic sprintGold Medalists Lennox Miller, Don Quarrie, Mel Patton and Quincy Watts. Along with brother Michael he also is on the school record holding 4x100 metres relay team. Sanford originally considered himself a 200/400 metres runner and it was only in 1979 that he started to concentrate on the 100 meters. This change resulted in wins that year in the NCAA championships and US National Championships 100 meters events. The win in the national championships qualified Sanford for the USA team at the 1979 IAAF World Cup where he became champion at 100 metres. Sanford picked up a muscle injury in a race in Berlin seven days earlier and was a doubt to run. It was also suggested that he anchor the United States4 × 100 m relay team but in the end United States team coach, Sam Bell, favoured the experience of Steve Riddick. Sanford was considered the favorite in the lead-up to the 1980 Summer Olympics boycott-marred United States Olympic Trials. However, he suffered an early-season defeat by a young Carl Lewis, then finished third in the 100 metres at the NCAA championships before finally injuring himself in the 200 metres there, ending his season. On May 11, 1980 at a meet in Westwood, Los Angeles, California, Sanford set the unofficial low altitude world record in the 100 metres at 10.02 s, a mark which stood for just over a year, when it was improved by Carl Lewis to 10.00 s. In 1981 he set the world's best year performance in the men's 200 metres clocking 20.20 s on 10 May at a meet in Westwood, Los Angeles.
