A Peek Behind the Coaching Process with Marni Sumbal, MS, RD, CSSD (Episode 141)

At this point, you may have been doing your sport for a decade, maybe two…or more. It’s easy to fall into a rut or lose your spark. The hormonal changes that come with the menopause transition also can make training more challenging and put a dent in your motivation. Trying a new challenge and/or working with a new coach can help you find your why and feel fired up again. This week, we pull back the curtain and talk about what that coaching process looks like as host Selene Yeager sits down with triathlon coach Marni Sumbal to talk through how they got Selene Ironman 70.3 ready after a 15-year hiatus from triathlon. Marni Sumbal is co-owner of Trimarni Coaching and Nutrition, a coaching and nutrition company based in Greenville, South Carolina, which she runs with her husband and RETUL bike fit expert, Karel Sumbal. Marni is a 3x author, board-certified sports dietitian, master of science in exercise physiology, 19x Ironman finisher, and 5x Ironman World Championship finisher. She was 5th in her age group at the 2021 Ironman World Championships in St. George and was 2017 Ironman Chattanooga First Place Overall Female Amateur.
