Career Highlights: After setting the American record in the 20-kilometer race walk at the U.S. Olympic trials with a time of 1:23:00.10, Barron didn't seem satisfied and quickly turned his attention to bigger goals. "I would love to make race walking more popular. But I need to be faster to do that," he said. "My time today is good but not great. I'm excited to be an Olympian, but that is not my ultimate goal. It is a means to greater things for me." The 19-year-old Barron should have plenty of years ahead of him to improve his performances, but for now he'll have to settle for breaking the U.S. mark previously held by his coach, former Olympian Tim Seaman, who finished in second place at the trials. It was the second straight national championship in the 20-kilometer race for Barron, who had successful brain surgery in 2006 to address a form of epilepsy. He later had to deal with people poking fun at his race-walking workouts, but eventually chose to try to raise the profile of the sport in the United States, which has never won an Olympic medal in the 20-kilometer race and has gone without one in the 50-kilometer event since 1972.
