The annual ASICS Los Angeles Marathon will bring gridlock worse than usual as huffing runners jaunt along the city streets this week.

Several street closures are expected along the marathon route, which will run across the city from Dodgers Stadium to Brentwood in West Los Angeles.

The marathon starts at 7 a.m. on Sunday, March 8 and runners will have six-and-a-half hours to finish the race. Traffic during that time will be diverted from the route.

Here’s how the 2026 Los Angeles Marathon will affect traffic.

Los Angeles Marathon Street Closures

Dozens of road, freeway and street closures will dot LA beginning as early as Saturday morning.

The majority of the road closures will be situated around downtown Los Angeles, according to a map. All of the closures will be around the route, which includes parts of downtown Los Angeles, Silver Lake, Hollywood, Beverly Hills, concluding in Century City.

Most road closures will start at 4 a.m. on Sunday and will end that night.

There are also numerous freeway ramp closures to the 101, 110 and 405. Those will be shorter-lived, with the final ramp reopening by 3 p.m. Sunday.

There will also be several roads not on the marathon route that will be closed to non-locals within downtown Los Angeles, Hollywood, West Hollywood, Beverly Hills and West Los Angeles. Locals can pull up to those road closures and ask for “local access.”

The closures are expected to worsen traffic temporarily in the Los Angeles area on Sunday. Race organizers said to expect “heavy traffic and delays on race morning.”

How many people run in the LA Marathon?

Marathon attendance will also likely worsen traffic in the area. More than 25,000 people are expected to run the race, and many are expected to spectate along the route.

The marathon is one of the largest in the country.

Security at the LA Marathon

While the Los Angeles Police Department could not confirm to The Post whether there would be additional security measures taken in light of the recent Iran airstrikes, there’s expected to be a security presence at the event.

City officials recently said the LAPD would bolster security “near places of worship, community spaces and other areas of the city.”

“We are closely monitoring for any threats to Los Angeles’ public safety amid military action in the Middle East,” Los Angeles Mayor Karen Bass’s office said in a statement.
