This week on Thriving Minds, I’m joined by Associate Professor Tara Walker, Senior Research Associate at the Queensland Brain Institute (UQ) — and co-host of the trail running podcast Trail Tales with Tara and Bryce.

Tara and I are both neuroscientists, and we both love running. In this episode we explore the science and the joy of trail running — what it does for brain health, mental health, confidence, and connection. We talk about why running on trails feels so different to road running, how being in nature changes the experience, and why community is often the missing ingredient for people who think “I’m not a runner.”

We also dive into Tara’s research program investigating how lifestyle interventions like exercise and diet support brain health, including what we’re learning about hippocampal neurogenesis, exercise-related blood factors (exokines), and the emerging idea of exercise mimetics — ways to mimic some of the benefits of exercise for people who can’t run.

Along the way, Tara shares her personal trail-running journey — from her first 10–12km trail race to ultras and 100km events, and the mindset and training strategies that make endurance possible. We also discuss injuries, why trail running is booming, and how moving outdoors can help us feel more regulated, less stressed, and more connected.

If you’ve ever felt disconnected, stuck at a desk, or unsure how to start moving again, this is a practical and hopeful conversation — grounded in real neuroscience and real life.

Listen now — and if you’re in Brisbane, you might even want to join a community run (koalas included).
