This week on The Back of the Pack Podcast, Kyle is off in Sydney, Australia chasing another World Marathon Major, so we are turning the microphone over to guest host Sierra Morris from The Run, Shattered Podcast. Sierra, also known as ShatteredRunner, brings her focus on mental skills, resilience, and the psychological side of running to a topic every runner needs: confidence. This episode dives into how confidence is built, why it matters in training, and how runners can strengthen their mindset before they ever reach the start line. Sierra explores the mental tools marathoners and ultramarathoners use to stay steady when races get hard, including visualization, breath work, mantras, preparation, and learning how to trust the work already done. Whether you are chasing a PR, attempting a new distance, coming back from a rough race, or just trying to believe you belong out there, this conversation is built for you. Confidence is not about pretending everything will go perfectly, it is about knowing you can handle the messy middle when things get uncomfortable. With Kyle halfway around the world and the Back of the Pack community watching the Sydney adventure unfold, this guest episode is the perfect reminder that running is never just about legs and lungs. Sometimes the biggest race-day breakthrough starts with what is happening between your ears.
