This Saturday, March 14th, is the DC Rock 'n' Roll Marathon (and half marathon / 5k). The race course starts by the Washington Monument, but much of the course runs through Capitol Hill. Although the race does not go through 6B06, be aware that travel to the north and west may be slowed or blocked due to runners. If you need to go west, you're probably best taking the 695. For details on closures and suggested routes, see the event website's page on road closures.
