Cambridge, MA
Entry is $40 now and rises to $42.50 after Oct 12, 2026, so registering before then saves $2.50.
The course runs along Mass Ave through downtown Cambridge, flat the whole way, which means there is nowhere to hide but also nowhere to lose time. Festive attire is encouraged, so expect a few elves and holiday costumes in the field. The post-race party includes drinks from a local brewery, which makes the finish area worth sticking around for.
