Kelly Fillnow Petrea


Kelly (USAT, RRCA certified) 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.) In 2016, she was inducted into the Davidson College Hall of Fame. Kelly also became a member of the Southern Conference 25th Anniversary Tennis Team.

After graduating from Davidson, Kelly ran for Duke University, then ranked #1 in the nation in cross country. While at Duke, she was honored as All-Region in cross country while the Blue Devils went on to win ACC’s and 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 debut. As an amateur, she finished on the podium in her two Ironman World Championship appearances, became a Duathlon Age Group National and World Champion, and set an American amateur Ironman record in her third Ironman in 9:29:49. As a professional triathlete, Kelly has placed as high as 3rd in both the 70.3 and Ironman distances. After tearing her ACL/meniscus while cheering for her athletes at a race, through arduous work and dedication, she came back stronger than ever. She PR’d in every distance from the Olympic to the Ironman in 2021. In 2022, she went on to compete in all three Ironman and 70.3 world championships at the professional level, finishing as high as 15th in the world. 

Kelly is passionate about helping people achieve their dreams and discovering the greatness within them. She has coached a National Age Group Champion, World Championship qualifiers, World Championship podium athletes, amateur Ironman and 70.3 champions, and helped athletes who could not run more than two minutes to crossing marathon finish lines. She believes anyone can reach beyond what they dare to dream through consistent hard work and self-efficacy.
