In this episode, Keely, Corrine, and Hillary discuss various life events and races before delving into recent research. First, they explore the current state of menstrual cycle research, highlighting areas of improvement and those that still have a way to go. They then discuss the impact of menstrual-related symptoms on mental health and spatial performance. As coaches, they share their approaches to addressing the menstrual cycle for athletes who menstruate, including tracking the cycle and adapting training to meet individual athletes' specific needs. Finally, they touch on Low Energy Availability (LEA) and RED-S, highlighting recent research showing that LEA can manifest in as little as 3 days. They also discuss coaching strategies for helping athletes recover from short-term and long-term LEA periods. Disclaimer: This podcast does not provide medical advice, but rather shares recent information in these two areas. Listeners are advised to always discuss their unique needs with a licensed professional.

In this episode, Keely, Corrine, and Hillary discuss their experiences at both the Western States 100 and Lavaredo trail races from last weekend. They kick off the episode by talking about the “Here for the Women’s Race” movement at the Western States 100 and then dive into a viewer question about hiking versus running on steep terrain and how to determine when one is more efficient than the other.

The Western States 100 produced the fastest times in history, with Katie Schide and Jim Walmsley winning the women’s and men’s race, respectively, in the second fastest times in course history. They talk about the rest of the field, fun storylines, and Keely talks through her experience pacing Rachel Drake to a top 10 finish. Disclaimer: they got skunked!

We are officially in trail racing season! This episode contains a lot of valuable information. Keely discusses a couple of recent studies. The first study focuses on master’s level trail runners and body image, while the second covers the performance detriments associated with Low Energy Availability in female athletes. Then Corrine and Hillary delve into race results, covering the Cocodona 250, Tillamook Burn weekend, Transvulcania, and some UTMB races. After that, they all reflect on their respective races at Transvulcania, discussing the highs and lows, mental health going into the race, and fueling wins and losses. Finally, they end with some society slams and advice for female athletes navigating health challenges.

They discussed Katie's journey into running, which started in New Hampshire's Black Mountains. They also talked about her transition to life as a full-time athlete and how she balances the newfound pressure to perform in a sport she loves. Katie shared her experiences of winning the Canyons 100k race in an impressive manner and also winning UTMB, a 100-mile race, while finishing second at the Western States 100-mile race last year. She also discussed her relationship with a fellow professional athlete and how they balance and support each other's goals. Additionally, they got an explanation about her "Cool Dad" nickname and asked her some rapid-fire questions to get to know her better, including her carbohydrate intake, favorite shoes, geomorphic features, and snacks.

In Episode 72, we are joined by Dr. Emily Kraus, a Clinical Assistant Professor at Stanford Children's Orthopedic and Sports Medicine Center. She is trained in Physical Medicine and Rehabilitation (PM&R) sports medicine and is also the director of the FASTR program. FASTR stands for Female Athlete Science and Translational Research, which is dedicated to closing the gender gap in sports science research. The program emphasizes early identification and interventions to prevent injury and optimize performance in female athletes.

During the episode, we discuss Dr. Kraus's journey to becoming a physician who focuses on female athlete health. We also talk about how the lack of female representation in sports medicine motivated her to pursue this career. We explore how increasing female representation in sports medicine can positively impact athletes.

Dr. Kraus shares how working as both a clinician and scientist allows her to better understand female athletes and apply findings in the clinic. We delve into coaching female athletes to return to sport from low energy availability and bone stress injuries and how to balance volume and load while also ensuring the athlete's health and safety.
