Mary-Katherine Fleming   Fitness Protection, LLC

I've been running since I was 6 years old, joining my dad's cardio rehab following a quintuple bypass. 35 years later I still run the same way his cardiologist recommended. Running is the best part of my life and I hope we can make it the best part of yours, too!


Mary-Katherine Fleming fell in love with running as an outlet from her intense life in finance, completing marathons and ultra-marathons all over Europe and Asia beginning in 2001. An RRCA certified coach, she continues to share her passion for running and works with runners of all levels and backgrounds, instilling her focus and drive in all aspects of training. She sees running as a 'lifestyle choice' and loves helping others orient their daily routines around athletic goals. She lives in Denver with her husband and 4 children.
