Kelly spent her childhood going from morning gymnastics meets, to afternoon soccer practices, and then to evening softball games. During high school, she trained at Van der Meer tennis academy in Hilton Head Island with her twin sister and older brother.

She received a scholarship to Davidson College and played number one singles and doubles for four straight years. While in college, she discovered a love for running and joined the cross country team. She ended up leading Davidson College to their first ever Southern Conference title and finished her career as a 10 time All Conference Honoree in tennis and cross country, while graduating cum laude. While at Davidson, she was awarded the Helen DeVane Carnegie Award (presented to Davidson’s most outstanding freshman) and the Rebecca A. Stimson Award (honoring the college’s top female athlete.) Kelly was selected to be a part of the Southern Conference 25th Anniversary Tennis Team. In 2016, she was inducted into the Davidson College Hall of Fame, becoming the youngest nominee in college history.

After graduating from Davidson, Kelly ran for Duke University, then ranked #1 in the nation in cross country. While at Duke, she finished All-Region in cross country while the Blue Devils went on to win ACC’s, Regionals, and placed third at NCAA’s.

A few years after college, she stumbled into triathlon and finished 3rd in her first triathlon. She went on to win her first half ironman, and then she qualified for the Hawaii Ironman World Championships in her first Ironman in 10:16. She finished on the podium in her two Hawaii Ironman appearances, became a Duathlon Age Group World Champion, a Duathlon National Age Group Champion, and set the American amateur Ironman record in her third Ironman. Kelly turned professional after numerous amateur titles. She finished 2017 with three top 5 Ironman finishes, including a 5th at Ironman Chattanooga, Ironman Austria, and a 4th at Ironman Louisville. She is grateful for her sponsors helping her chase her dreams.
