SAN FRANCISCO (AP) -- Iconic San Francisco footrace Bay to Breakers is set to kick off Sunday, with more than 100,000 spectators expected to watch about 40,000 runners compete for more than $70,000 in prize money.
This year marks the 103rd anniversary of the more than 7-mile race, which is one of the oldest in the nation.
The event has long been known for its colorful costumes, nude runners and a decadent, party-like atmosphere.
Alcohol, wheeled objects like strollers and skateboards, and certain types of bags and containers will be banned from the race course as officials maintain heightened security in the wake of the 2013 Boston Marathon bombings.
Race owner Wasserman Media Group says there will be a 20 percent increase in security personnel to ensure the safety of participants and spectators.
