Breathing is something we do every moment of every day, yet most runners never give it a second thought. If you've ever found yourself gasping for air during an easy run, battling a painful side stitch, or wondering whether you're "supposed" to breathe through your nose, this episode is for you.

In this conversation, Angie and Kevin explore why breathing is one of the most overlooked skills in running—and one that can have a surprisingly big impact on how your runs feel. They explain why breathing isn't about chasing perfection or overthinking every inhale and exhale. Instead, it's about helping your body work more efficiently so running feels smoother, easier, and more sustainable.

You'll learn how your breathing influences everything from endurance and running economy to nervous system regulation and recovery. Angie also shares why learning to use your diaphragm changed her own running experience, while Kevin explains the simple techniques that helped him overcome side stitches early in his running journey. Whether you're a brand-new runner or someone who's been logging miles for years, this episode offers practical tools that can improve both your running and everyday life.
