Shannon's second season as a Gamecock harrier was another successful one. Once again, she was a top seven runner of the team, competing in all of team's races in 2009.
Shannon had a great start to her freshman cross country season in 2008, running a PR 18:58 in her first race as a Gamecock and equaling her efforts in the team's second race on a hillier course. She was then hampered by severe cramping during workouts and races with what turned out to be several internal cysts, one of which ruptured. With her health problems behind her, Walls should continue with the great improvement she showed last year in the early season.
In high school, she earned four letters in cross country (2004-07). She received the Wendy's Heisman Award in 2007 and was Academic All-Ohio in 2007. A 2007 state qualifier and four-time first-team all-conference selection (2004-07), Walls was Honorable Mention All-Southwest Ohio (2005-07) and OHSAA Scholar-Athlete of the Year.
The summer before her freshman year, she went on her fourth mission trip to Mon Valley, Pennsylvania. She is the daughter of Dan and Michelle Walls.
