About Me

Hey there! I’m Dr. Will O’Connor. With a PhD in sports science and countless miles under my belt, my life’s work is all about blending the art of running with solid scientific principles.

Running isn’t just a sport for me; it’s a way of life. From those early morning runs that kickstarted my day to the ultra-marathons that test my limits, every step is a story. And it’s these stories, combined with a deep dive into exercise science, that I bring to you.

My mission? Simple. To make you a faster, more informed runner. Whether you’re just starting out and struggling to find your rhythm, or you’re a seasoned runner chasing a new personal best, I’m here to guide you. I believe in making the complex simple, turning scientific insights into actionable, everyday tips.

But it’s not all about the grind. I firmly believe in balance—mixing rigorous training with the rest of life’s demands. Because let’s face it, we’re not just runners; we’re parents, professionals, and friends, all rolled into one. Staying healthy, avoiding injury, and preventing burnout are just as important as the training itself.

So, whether you’ve heard me on my podcast, seen me on YouTube, or are just discovering me now, welcome. I’m thrilled to have you on this journey. Together, we’ll explore the science of running, celebrate the victories, and, most importantly, enjoy the run.
