Nike Pacific Head Run Coach, competitive trail runner, and Femmi co-founder Lydia O’Donnell sits down to talk about unlearning toxic fitness norms and rebuilding a sustainable, empowering relationship with movement. Lydia opens up about navigating disordered eating, losing her menstrual cycle during her elite road racing career, and the life-changing pivot to cycle-based training sparked by Dr. Stacy Sims’ ROAR.

She also takes us behind the scenes of founding Femmi in a male-dominated tech landscape, navigating capital raising, weathering layoffs, and coping with the grief of losing her father while managing a startup. Plus, Lydia breaks down the biggest misconceptions around training through your period and shares the mindset shifts required to run for longevity rather than comparison.

IN THIS EPISODE

• Trail Running as a Reset: How shifting from 20 years of competitive road and track racing to technical trail distances (from 21K up to 50K) helped Lydia rediscover pure playfulness and stripped away external pacing pressures.

• The Toll of Disordered Eating & RED-S: Confronting the damaging myth that "smaller equals faster," surviving restrictive habits, and the hospital wake-up call that forced Lydia to prioritize hormone health over aesthetics.

• Cycle-Based Physiology: The turning point of learning female physiology through Dr. Stacy Sims’ research, why cycle tracking is a competitive advantage, and why your period is actually a high-performance window.

• Building Femmi in Tech: The grit required to scale an app designed specifically for women when less than 2% of VC funding goes to female founders, alongside the painful realities of team restructuring.

• Movement Through Grief: How running served as a daily sanctuary and emotional release while caring for her father during his battle with brain cancer.

• Sustainability Over Speed: The danger of chasing arbitrary metrics on apps like Strava and the essential questions every runner should be asking instead: How do I stay consistent, and how do I become a sustainable athlete?

QUOTABLE MOMENTS

"The thing that's going to make you a faster athlete is consistency in your training. And to get consistency in your training, you need to fuel properly, sleep properly, and do all the good things."

"Running doesn't guarantee you anything; it doesn't owe you anything. All you can focus on is yourself, your strengths, and your superpowers."

"We grew up speaking so negatively about our periods... but changing that conversation to 'I’m healthy, my risk of injury is lower, things are clicking' turns it into a celebration. Let’s go train hard."
