Being able to run a half marathon is something I don’t take for granted — it is a true privilege. Not everyone has that freedom. That’s why I want to turn every mile into something meaningful for those whose lives have been turned upside down by cancer.

Cancer is devastating. It steals time, dreams, and certainty — especially from young adults who are just beginning to build their future. No one should have to face that battle alone.

With every step, I’m running for the Allyson Whitney Foundation, helping provide support, resources, and hope to young adults fighting cancer.

Thank you for giving my miles a purpose. Your donation truly changes lives
