Coming October 2, 2016. Do I smell beer and pretzels? It must be the Cambridge 5K – Oktoberfest! A fun, fast race in downtown Cambridge (Massachusetts, that is!) followed by an even funner Oktoberfest celebration. The post-race party includes music, local beer and cider, fresh baked pretzels, and delicious German food. Dust off the dirndls and lederhosen and sign up for the Cambridge 5K – Oktoberfest!
