Runners will hit the road for the 36th annual San Francisco Marathon early Sunday morning and security will be tight following this year's attack at the Boston Marathon.
Getting around the city Sunday morning could be difficult, with various street closures and runners were told to come extra early for security checks.
For the first time, the start and finish lines on the Embarcadero between Folsom and Mission streets, will be completely enclosed with police officers, bomb sniffing dogs and all bags will be searched.
Runners browsing the booths at the pre-race expo Saturday said they know they could bunch up getting through security, but it's a small price for safety.
“I'm running my first marathon tomorrow and (Boston) will be in the back of my mind,” said Palm Springs resident Sandy Pearson.
As with last month's Bay to Breakers race, marathoners will also have to check in any bag or backpack bigger than a piece of binder paper.
Rosters show the 20,000 participants registered, about 5,000 fewer than most years, but the event had to be held more than a month earlier than usual.
“Our permits conflicted with the America's Cup sailing, so we bumped it up about six weeks so we could still have the event,” said Joanna Reuland, with the Wipro San Francisco Marathon.
A group of half-marathoners at Saturday's expo said they were worried a bit about the hills and the chill, but they are looking forward most to running across the Golden Gate Bridge.
“When else are you ever going get to run across the bridge like a crazy person in the middle of the bridge with no traffic whatsoever, and I also heard that the bridge is going to shake,” said Parineeta Kuntamukkala, a San Jose resident.
Set Soto of San Jose said he's dedicating his sixth marathon to the people of Boston and the strength they've shown.
“Doesn't matter, just keep going, whatever obstacle comes your way, just run right through it,” Soto said.
Starting at midnight the Embarcadero will be shut down between Harrison and Broadway for preparations.
The race begins at 5:30 a.m. on Embarcadero at Mission Street.
The full marathon will take runners across the city and over the Golden Gate Bridge.
Many of the street closures will lifted by mid-morning Sunday, others in the early afternoon.
Watchdogs are questioning an exclusive agreement between the City of Oakland and a non-profit group, tapped to lead a multi-million dollar project to redevelop the area around the Coliseum BART station.
