Thousands of runners descended on the District on Saturday for the Rock 'N' Roll marathon.

The event has been going on for more than 20 years, and it features live bands and cheer squads along the route.

The run begins along Constitution Avenue and runners make their way through several D.C. neighborhoods and eventually end at RFK stadium.

Around 17,000 runners participate every year.
