DC Metro Safeguards C77 Service During Marathon Prep

WMATA's C77 bus route detours temporarily for Rock N Roll Marathon 2026 preparations

C77 Bus Route Detours for Marathon Prep

WMATA's C77 bus route will take a temporary detour as the transit agency prepares for the Rock N Roll Marathon 2026, officials said Friday. The service change affects commuters traveling through areas where marathon preparations are underway, though officials haven't specified which streets will see detours. The agency classified the disruption as high severity and announced the change February 28.

Marathon Preparations Drive Service Changes

The detour stems from logistical preparations needed to host the major running event, which typically draws thousands of participants and spectators to the DC-Maryland-Virginia region. Transit agencies routinely adjust bus routes around large-scale events to accommodate road closures, staging areas, and crowd management needs. Officials said the changes aim to maintain service while allowing event organizers to set up infrastructure along the marathon course. The Rock N Roll Marathon series has become a fixture in major cities, requiring coordination between transit agencies, police, and event planners.

Detour Specifics Remain Limited

WMATA didn't provide detailed information about which specific streets the C77 will use during the detour or how much additional travel time riders should expect. Officials also haven't said whether the detour will affect all trips on the route or only certain time periods. The agency typically posts detour maps and alternative stop locations for affected routes, though that information wasn't available in the initial announcement. Transit officials said riders should allow extra time for their commutes while the detour remains in effect.

Duration and Timeline Unclear

Officials announced the detour February 28 but didn't specify when it will end or how long marathon preparations will require the route change. Marathon events typically need several days to a week for setup and teardown of course infrastructure, but whether the C77 detour will last that long wasn't clear. The agency said it'll provide updates as the situation develops.

Riders Urged to Check for Updates

Commuters who regularly use the C77 should plan for potential delays and check for service updates before traveling. WMATA officials said passengers can find current detour information and alternative travel options through the agency's service status system.
