Melissa Kahn, a Jenny Craig brand ambassador, half-marathon runner and mother of four, founded the online community called Run, Heifer, Run! as a way to connect with and encourage others who are on the journey to healthier and happier lives, one step or mile at a time. Five years ago, Melissa cut the bull and got serious about her health. Starting with a few steps, she lost over 110 pounds, worked her way up to running races and even completed a triathlon. She cleaned up her diet, shed weight and ultimately found a fitness enthusiast underneath her extra baggage.Melissa does all of this from her heiferhood in sunny Phoenix, where her husband, teenagers and two crazy puppies remind her that we're all a little happier in a herd.
