Here is a guide to Sunday's L.A. Marathon:
Scott Sukup of the National Weather Service in Oxnard said that the temperature around race time Sunday in downtown L.A. will likely be in the mid-50s and then heat up into the low 80s later in the day.
"It should be a pretty nice day — warm, it'll be warm by the afternoon," Sukup said.
The street closures will be in various places in Los Angeles, West Hollywood, Beverly Hills and Santa Monica.
To try to ward off congestion and commuter frustration, marathon officials have issued a course closure grid, a map of additional streets that will be closed on Sunday and various other maps and tools to navigate across the county that morning.
L.A. Marathon organizers warned that road closures will begin at 3 a.m. and be in full effect three hours later. Crossing the course will not be permitted. The race begins at 7 a.m., with streets reopening on a rolling basis as approved by public safety officials.
Freeways around Los Angeles County mostly will be unaffected by the closures, save for some ramps that will be shut down for several hours.
Officials in West Hollywood and other cities along the route are also sending out advisories to residents regarding street closures, and suggesting the public follow local official Twitter accounts for announcements as streets reopen.
There is also a map on Commuterama.com that is designed to help motorists avoid the closures and let those who want to cheer on the marathoners know how they can navigate the route.
TIMING (A bit early)
Clocks spring forward an hour for daylight saving time at 2 a.m. Sunday.
CYCLISTS (Ride back on)
Cyclists, who earlier this week were told they could not ride before the race began, got a reprieve Saturday.
Don Ward, organizer of the bicycling group Wolfpack Hustle and the annual Marathon Crash Race, credited officials from the Los Angeles Police Department, the city attorney’s office and the mayor’s office as key players in helping to obtain a permit to make Sunday's ride a reality. Ward announced the cancellation of the popular predawn race along the Los Angeles Marathon route earlier this week because of a lack of proper permits.
Yusef Robb, Mayor Eric Garcetti’s spokesman, confirmed that the Los Angeles Bureau of Street Services had issued the new permit. He declined further comment.
Participants in Sunday's so-called fun ride will still be able to trace the 26.2-mile route, but there will be no racing competition this year, Ward said. The city permit allows for riders to go 10 to 15 mph., he said.
