Stone celebrated her 13th birthday and the following day began competing by winning the 100-meter backstroke, finishing second in the 800-meter freestyle and placing fourth in the 50-meter freestyle. She swam the 200-meter backstroke, placing first, and also placed third in the 400-meter freestyle that same day.

Stone qualified for the finals in two events - the 100-meter freestyle and 100-meter butterfly - and then won the 1,500-meter freestyle finals in 23 minutes, 45.61 seconds, breaking her own record by two minutes. She then placed third in the finals of both the 100 freestyle and 100 butterfly events, ending her busy weekend.

Elizabeth was born with Proximal Femoral Focal Deficiency - her femur is extremely short - and she had four surgeries to correct the situation. She later had her foot amputated, according to her mother, Linda. This disability qualifies her as a S-9 swimmer (those with above-knee or below-elbow amputations are also in that category).

A seventh grader at West Side Christian School in Grand Rapids, Stone has been a competitive swimmer for four years and plays wheelchair basketball during the winter, competing with a team that finished third in the nation in the junior division.

Although she often swims in competitions for the disabled, Stone normally competes with an able-bodied USA Swimming club team in Grand Rapids called the Rockford Riptide and has competed favorably with girls in her age group. In March, she was clocked at the "A" level times in the 50 backstroke and 200 backstroke, which put her among the best in Michigan in the 11-12-year old division.
