Episode 285: Some News, Some Tears, & a Discussion on Red-S with Physical Therapist Cat Fitzgerald.

After a big announcement and a conversation about recent races, we welcome Cat Fitzgerald, PT, of Custom Performance in New York City , for an important discussion about underfueling, Relative Energy Deficiency in Sport (RED-S), and injury risk in runners.

Cat explains how insufficient energy intake can affect recovery, bone health, hormones, performance, and the body’s ability to withstand training. They discuss signs that a runner may be underfueling, why RED-S is not limited to athletes in a particular body type or at a particular level, and how runners can better support their training through adequate nutrition and recovery.

Cat Fitzgerald is a physical therapist with Custom Performance, a New York–based practice that helps athletes return to sport, build resilience, and stay healthy through individualized physical therapy and performance care. Learn more about Custom Performance at customperformancept.com.
