believes it is the best sport for overall conditioning of
one's body that can be picked up throughout one's life. Her
competitive swimming began at Bolton Hill Swim and Tennis as a
young child specializing in breaststroke, "the best-stroke". Though
her college did not have a swim team she continued to swim and
integrate it in her training for marathons as well as triathlons.
