The 15th annual BAA 5K features an urban course that takes 10,000 runners past historic Boston landmarks and across the Boston Marathon finish line. In 2017, Ben True again set the American men's 5K record on this very course! The B.A.A. 5K serves as the first race of the B.A.A. Distance Medley, a three-race series that also includes June's B.A.A. 10K and October's B.A.A. Half Marathon.

Also scheduled on April 13 is the 15th annual BAA Invitational Mile. Top scholastic boys and girls from the cities and towns of the Boston Marathon course, as well as a field of professional male and female milers from around the world, take off in the B.A.A. Invitational Mile on marathon weekend. Bleacher seating at the finish line is free and open to the public.
