Now set for its third annual running through the Twin Cities area, the Red, White & Boom! TC Half Marathon is organized by Twin Cities in Motion, whose other local race events include the annual Twin Cities Marathon. This 13.1-mile race is timed to coincide with the 4th of July holiday, and features long stretches of the course through the parks that parallel the Mississippi River, which flows through the heart of the city. Limited to 3,000 runners, the race will follow an out-and-back course that starts and finishes on Main Street Northeast near the Saint Anthony Falls and Father Hennepin Bluffs Park, which lies along the riverbank near the Mississippi National River and Recreation Area, a series of parks along the river that stretch more than 70 miles.
