After a standout high school career for Marble Falls High School (Marble Falls, Texas), where he won a total of nine state championships, Manzano went on to compete for the University of Texas. He holds school records in the indoor mile and 1,500 meters.
In 2012, he won the 1500 meters at the USA Indoor championships and the U.S. Olympic Trials to earn his trip to London.
