Mackenzie Kelly

Running has been a part of my life since I was 7 — from track and cross country at Boston Latin to countless half marathons. It’s taught me resilience, strength, and purpose. Now, I’m taking on my first full marathon to give back through the sport that’s shaped me. Years ago, Chris Herren spoke at my high school and shared his story — one that opened my eyes to the realities of addiction and the power of recovery. His message still inspires me today. Every mile I run is for those still fighting, those in recovery, and those we’ve lost. Thank you for your support.
