Tenth Annual Ras na hEireann U.S.A. 5Km—One of the Biggest St. Patrick’s Day Races in the NationRegistration is now open! Running in Somerville, Massachusetts, on March 10, 2013, Ras na hEireann U.S.A 5Km is the most genuine Irish race this side of the Atlantic. More pubs this year--many with live music-means an even better celebration of traditions dating back centuries—a celebration of spring in Somerville, but limited to only 5,000.
