Update: Bay to Breakers will still go on despite the rainy weather set to descend on today’s race.

The 108th annual Bay to Breakers, a footrace of costumery and alcohol-driven shenanigans, happens today. The race will result in numerous street closures and traffic reroutes throughout most of San Francisco.

Be prepared.

The race begins at 8 a.m. at Howard and Main in the East Cut, following Howard up to Ninth Street, then up Hayes from Market to Divisadero, onto Fell from Divisadero to Golden Gate Park. Once in the park, runners will follow JFK Drive all the way to Great Highway. (Phew.)

There will also be a bonus route running an additional 5K south on Great Highway, should the mood strike.

Once the main race begins, travelers will only have two options to cross the north/south portion of the race course: The Embarcadero and Crossover Drive (which connects 19th Avenue, south of Golden Gate Park to Park Presidio Boulevard and 25th Avenue, north of Golden Gate Park).

Regarding street closures: We strongly recommend not using your personal vehicle at all in the city. Traffic will be a mess, to say the least. Here are the street closures happening on Sunday:
