Plenty of road races finish near Fenway Park; this one finishes inside it. The Run to Home Base sends a 9K run and a 5K run/walk through Boston’s streets before funneling the whole field into the ballpark and across home plate — a finish no other local race can offer, and one that gets emotional fast given who everyone is running for.

The event is the flagship fundraiser for Home Base, the Red Sox Foundation and Massachusetts General Hospital program providing clinical care and support to veterans, service members, and military families dealing with the invisible wounds of service. Participants commit to fundraising on top of registering, and the field mixes serious runners, walking teams, and families honoring someone they love. If you want a race where the cause is front and center — and a Fenway moment you can’t buy — this is it.
