The SunTrust Rock 'n' Roll USA Marathon, formerly known as the National Marathon, is an annual marathon and half marathon held in Washington, D.C. It was established in 2006 as an annual event. It was organized by the Greater Washington Sports Alliance and was sold to Competitor Group, Inc. in 2011 to become part of their Rock 'n' Roll Marathon Series
The 42.195-kilometre (26.219 mi) course starts and finishes at RFK Stadium and the number of participants was limited to 8,000 in 2008. The course for the first running of the race was in Washington, D.C. and Prince George's County, Maryland, but altered in 2007 for the course to be run entirely within the District of Columbia. The race in 2008 and thereafter passes through 6 of the District's 8 wards.
In 2007, the National Marathon was sponsored by Wirefly, an online cell phone retailer. In 2008, SunTrust Banks became the race's primary sponsor.
Starting and finishing at RFK Stadium, this is the only marathon to run entirely in Washington, D.C. 20,000 runners will enjoy a scenic journey through our Nation's capital, running through downtown DC, various quaint neighborhoods, historic sites such as Union Station and the National Mall with a view of the White House, and along the Anacostia River.
