2019 Somerville 5K Race Directory

Many Somerville 5K races take place in Davis Square, though Assembly Row and the DCR Blessing of the Bay boat house on The Mystic River have become popular for races over the past few years.

Somerville races range from a few hundred to a few thousand runners. Some are party events geared towards a younger crowd, and some are family oriented and great to bring your kids to.

The list of Somerville 5K races changes yearly. Races get cancelled or postponed and occasionally a new race appears on the scene.

Between the Green Line extension and normal construction some races have been moved, postponed or both. Hopefully things will settle down in a year or two.

As such, be sure to check back for race updates. If you are managing a race that is not on this list, send your information to –

Ras Na Heirnann 5K, Somerville 5K raceDue to construction this race has been cancelled for 2019.

In 2018 this race had 1,340 finishers. Based in Davis Square the Rás na hÉireann in one of Somerville’s largest 5K races.

Due to major construction on Somerville Ave and the Ball Square Bridge, we are postponing the 2019 race. It will be moving to September 15th as a HalfWay to Ras nahEireann USA. Stay tuned for updates!Race Director

This race draws some of the best 5K runners in New England. In 2018 the top four runners ran a 5:00 or less pace! 37 runners ran a 6:00 or less pace.

Many hundreds more ran your pace. So don’t be intimidated.

Mark Kenneally of Dublin, Ireland, set the course record of 14:19 in 2006. Molly Huddle, of Providence, Rhode Island, set the women’s course record of 15:59 in 2010.

So if you want to compete with some of the best 5K runners around or just go for a fun run with your friends, this mid-September race is for you.

With a strong St. Patty’s and Irish theme, this race attracts a young crowd and is always a great time. I do see a few kids in strollers, but this is generally not a family focused event.

Somerville Homeless Coalition Road Race

6 October 2019 9:00 AM  Sunday

2019 ws the 24th year for this 5K! The race starts behind Arlington High School.

Registration was $30. Raise $150 and your registration is FREE. Raise $300, get FREE registration and a runner’s cap! They will even help you set up a fundraising page.

There will be plenty of parking at the high school. There is a fantastic brunch served after this race, which alone is worth the price of admission!

I ran this race three or four years ago and recall that it was around 1,000 runners and certainly not 3,000. I would recommend this race for the kids.
