The LA Marathon is an annual 26.2 mile running event held each spring in Los Angeles California. The Marathon's route passes through some of LA's most famous landmarks and diverse neighborhoods with festivities all along the course. Block parties with live performances are spaced along the route to entertain fans while they wait for runners to pass. This year will mark the 28th anniversary of the Marathon. The Waze community has updated the map with significant road closures and will continue to add hazards as they unfold in real-time.
