Annual Bay to Breakers Race
Sunday, May 17: The annual Bay to Breakers Race will take place. The SFMTA will provide special Muni service to help Bay to Breakers participants and non-participants to get where they need to go.
Bay to Breakers’ unique geography cuts the city in half and provides only two crossing points for buses and vehicles (The Embarcadero and Crossover Drive). As a result, many Muni bus lines are divided into two parts – one on either side of the race. The easiest and fastest way to travel during Bay to Breakers is to stay on one side of the race route. For a real need to cross the route, the fastest ways are to use a train or to incorporate walking or rolling across the race route. Muni Metro Subway Lines J Church, K Ingleside, M Ocean View, N Judah, and S Shuttle; T Third Street in the Central Subway and BART are recommended for crossing under the race route without delay, and Muni’s bus routes will carry passengers as close as possible to the race route so they can cross “on foot” and pick the bus route back up on the other side.
This year Muni is excited to announce that early morning train service is back to help runners get to the Bay to Breakers starting line. Muni’s Bay to Breakers transit service plan is as follows:
