In this episode of the Female Athlete Nutrition podcast, I talk with professional trail runner, coach, podcast host, and physiologist, Corrine Malcolm. We start by exploring Corrine’s childhood in Wisconsin, growing up a very active kid, involved in sports from early on. Corrine shares how her competitive spark was ignited, playing a variety of sports through high school and in college. We hear Corrine’s remarkable story of playing on two different NCAA college teams: cross country skiing and track. She discusses some of the challenges of being on a competitive collegiate team, including how team politics kept her from racing nationals.  With her eyes on the Winter Olympics, Corrine explains her decision to drop out of college and join the US biathlon team. A mix of cross country skiing and shooting, Corrine’s training increased dramatically and it wasn’t long before Corrine started to feel the effects. Corrine talks about the team cultures within college and professional settings she’s been a part of, and how that influenced her physical and mental health. We define overtraining syndrome (OTS), the signs and symptoms, and how to avoid it. Athletes with OTS are no longer benefiting from their training, and a couple rest day won’t solve it. Corrine shares her story with overtraining syndrome, even without RED-S or underfueling, that left her chronically fatigued and resenting the sport. We touch on the overlap between RED-S and OTS, while highlighting that they are independent conditions. Corrine opens up about the psychological symptoms of OTS, poor training, underperformance, and anemia that she experienced: OTS is all an encompassing physiological, metabolic, and mental condition. We discuss recovery from OTS: Corrine was forced to retire from biathlon prior to the Olympics and step away from all sport for 18 months. We hear about Corrine’s return to competitive sport, this time in trail and ultra running, and how she is using the lessons she’s learned along the way to help her and others succeed today. Corrine normalizes taking time off and sharing the struggles, both in this episode and on her own podcast the Trail Society. Corrine and I discuss staying fueled even with a busy schedule, including great strategies perfect for high school and college athletes, as well as us moms and working professionals. Corrine shares how she currently prioritizes her nutrition within and around workouts by planning ahead and preparing snacks and recovery shakes in advance. We emphasize the importance of avoiding within-day energy deficits, starting with eating around morning workouts. Corrine advises listeners that being busy is not an excuse for underfueling, and coffee is not breakfast! Corrine Malcolm’s Official Bio: Corrine is a coach, physiologist, writer and newly minted editor-in-chief for FreeTrail, podcast host, and a professional runner for Adidas Terrex. Corrine takes after her mom -an emergency medicine doctor, medical director, and violin teacher- in that she feels she has to do a little bit of everything. Corrine says she has vexed many teachers, coaches, and parents with her need to know "why" - but that same impulse drives everything she does. Corrine has been an NCAA athlete in two sports: skiing and running, a national team member in both biathlon and trail running, dropped out of college twice, coached endurance sports for a decade, and most recently she has helped launch live broadcast commentary for trail and ultra running at races like the Western States Endurance Run (WSER) and Ultra-Trail du Mont-Blanc (UTMB).
