Larson opened her 2009 season at the Gymnix World Cup and earned gold medals on beam and floor. She was selected as part of the European Tour. She did not compete all-around but helped the team win against Germany and France. Larson suffered a double-ankle sprain shortly before the 2009 U.S. National Championships. Thus, she was unable to compete and did not recover in time to secure a bid to the 2009 World Championships.
