I've run the BAA 10K 3 times and I can say it never disappoints! It is super well-organized, and even with 10,000 runners, it never felt too crowded. The volunteers, especially at the water stops, were awesome and super encouraging! And the course itself is a great little out and back tour of Boston’s Back Bay, Kenmore Square, and part of the BU campus.
The Boston Athletic Association always puts on a great race. The start/finish location lends itself nicely to taking public transportation. There are also plenty of parking garages nearby. Gear check was super efficient, and the post-race food was plentiful. And, how can you not love the Unicorn medal?!
