2015 B.A.A. 5K

In 2009, the first annual B.A.A. 5K was held a day prior to the Boston Marathon, giving runners a chance to kick off Boston Marathon weekend in grand style. Beginning in Copley Square and taking participants through Boston's Back Bay neighborhood, more than 3,500 athletes raced their way to the Boston Marathon finish line on Boylston Street, where the raced finished. In the years since, the B.A.A. 5K has been a memorable highlight of Boston Marathon weekend, getting people into the running spirit before Marathon Monday. 
With more and more people wanting to take part in the B.A.A. 5K, the race moved its start and finish from Boylston Street to Charles Street adjacent to Boston Common and the Boston Public Garden in 2014, accommodating a field size of 10,000. This year, the B.A.A. 5K will feature a slightly altered course, enhancing the race experience for all athletes while still giving runners the opportunity to cross the Boston Marathon finish line. 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. Many of the world's fastest runners participate in the B.A.A. Distance Medley each year.



The B.A.A. 5K is the first race of the 2015 B.A.A. Distance Medley, a three-race series which also includes the B.A.A. 10K on June 21 and the B.A.A. Half Marathon, presented by Dana-Farber Cancer Institute and the Jimmy Fund, on October 11. Registration for the B.A.A. 10K opens on May 6. Registration for the B.A.A. Half Marathon opens on July 15.

1920 - Ashland Start

The Boston Marathon began in Ashland, Massachusetts from 1897 through 1923 then moved to Hopkinton for the 1924 race. The course was lengthened to 26 miles, 385 yards to conform to the Olympic standard, and the starting line was moved west from Ashland to Hopkinton. Since then, the race has started in Hopkinton every year.
