Run, run as fast as you can; the Rock and Roll Half Marathon is about to take over the streets of downtown once again. Choose from a half marathon, a two-person relay or a mini marathon (also known as a 5k). Atlas Genius is set to headline the race, taking the stage for a post-race concert. Runners can also cool off with a well-deserved brew at the beer garden. Registration fees range from $40 for the mini to $105 for the half to $125 for the relay. Sept. 29 at 7am. Beginning at Gaspee Street and ending at Francis Street.
