It'll be a busy Saturday morning along the Embarcadero tomorrow -- what with 10,000 people running up and down the bay and across home plate at AT&T Park.
The annual Giant Race -- in which participants hoofing for 5K, 10K or half-marathon races (that's 3.1 miles, 6.2 miles or a whopping 13.1 miles or thereabouts) -- will snarl traffic, close city streets and shutter Muni lines for a few hours on Saturday, according to the San Francisco Appeal online newspaper.
The race will lead transit officials to close streets in the Embarcadero, along Fisherman's Wharf, Fort Mason and the Presidio throughout the morning, San Francisco Municipal Transportation Agency spokesman Paul Rose said.
Runners raise funds for Project Open Hand, which provides meals to seniors and folks with serious illnesses. But much more than charity is at stake -- participants in the race receive a Tim Lincecum bobblehead doll.
All roads are expected to reopen by 1 p.m.
