Good distance running requires a lot of training, as we know…. but training for running, swimming, AND cycling all at once? It takes an “Iron Man”… or “Woman”…  to do it all and win. And today on Running Around Charlotte we have not just one, but TWO Ironman champions and professional triathletes, who also just happen to share the same last name.. and at one point, even the same womb. Say Welcome to twin sisters Kelly and Meghan Fillnow, pro triathletes and owner & manager of Fillnow Coaching.
