Paddy's Classic 5K and Block Party

Paddy’s 5K isn’t just another Saturday morning dash—it’s a real investment in the next generation of Cambridge athletes. The course itself is a quick loop, but the impact stretches much further, with every registration fee helping fund local girls’ sports teams that don’t always get the spotlight (or the resources) they deserve. The post-race block party on Walden Street is a proper neighborhood hang, with a beer garden, food trucks and a DJ who keeps things lively well into the evening. It’s the kind of event where you’ll spot familiar faces from around town, whether they’re running, volunteering or just showing up for the party. If you’re looking for a way to support something meaningful and have a genuinely good time doing it, this is a solid pick. Plus, you can feel good about that second beer—after all, it’s for a great cause.
