SF Marathon Reroutes Muni Buses Sunday

San Francisco Muni riders should expect service changes Sunday as the San Francisco Half Marathon & 5K affects several bus routes. The race starts at 7:50 a.m. and winds through Golden Gate Park, the Panhandle, and along the Great Highway, prompting reroutes on four bus lines. Transit officials said riders should plan for delays and consider alternative routes during the morning hours.

Routes Affected by Race Course

The 18, 33, 43, and 44 bus routes will be rerouted to accommodate thousands of runners expected for the event, according to the transit agency. Officials didn't specify exact detour routes or how long the modifications will remain in effect. Special events requiring street closures typically affect transit service for several hours, with routes returning to normal once race participants clear the course and streets reopen. The race course covers some of the city's most scenic areas, requiring coordination between event organizers and transit operations.

Service Modifications During Event

Muni announced the changes through social media channels, though detailed information about specific stop closures and alternate boarding locations wasn't immediately available. Officials said riders should allow extra travel time Sunday morning if they're using affected routes. The transit agency typically posts detour maps and temporary stop locations closer to major events, but whether that information will be released before Sunday wasn't clear. Transit officials advised checking for updates before traveling.

Timeline for Sunday Morning

The race begins at 7:50 a.m. Sunday, January 31, with service disruptions expected to start earlier to accommodate course setup. Officials haven't said what time routes will return to normal service, though that typically depends on when the final runners finish and streets reopen. The transit agency said it coordinates with event organizers to minimize disruptions while ensuring runner safety.

Planning Your Sunday Trip

Riders traveling through Golden Gate Park, the Panhandle, or along the Great Highway Sunday morning should expect delays and possible crowding on alternate routes.
