Just saw this in an email regarding the "official" rules for Bay to Breakers this year.
So yeah... that was a fun San Francisco institution while it lasted.
Only REGISTERED participants will be ADMITTED to the Start and Finish areas. For everyone's safety and enjoyment NO ALCOHOL or NUDITY is allowed and there will be ALCOHOL CHECKPOINTS along the course. Additionally, no pets, roller blades, skateboards, bicycles, or plastic bags for warm-ups are allowed on course. Wheeled objects and over-sized costumes must line up at the back.
