The 2026 Los Angeles Marathon is set to take place this Sunday, with thousands expected to participate. Notably, runners will now receive finisher medals after completing just 18 miles due to anticipated high temperatures reaching 80 degrees. As the event approaches, major street and freeway ramp closures will impact traffic across West Los Angeles. A full list of road closures and a detailed course map are available for those planning to navigate the city during the marathon. Additionally, a vibrant atmosphere is expected with over 120 cheer zones, DJs, and mariachi bands along the route. Participants and spectators alike should prepare for significant delays and plan their travel accordingly.
