Road Closures

Most road closures and detours will be in effect between the hours of 6:00 am and 3:00 pm. At 6:00 am, Police and event personnel may implement a soft closure along the entire race course. At most points along the course, pedestrians and bicyclists may cross the course during safe gaps in runners. Please follow the discretion of a traffic controller if present. After the race starts the streets will reopen on a rolling basis as soon as the last participant has passed and all course support materials have been removed. Streets along the earlier miles of the route will open earlier than roads along the end of the route. Please review the course map and road closure grid for more information. Residents and businesses located near the race course are urged to plan ahead and to be aware of road closure schedules and alternate access routes.

Freeway and Ramp Closures

On Sunday, freeway and ramp closures associated with the courses may impact your travel on race day.  Please note, Interstate 5 will remain OPEN, in both directions. Please review our road closure grid for more information. Note, these closures and times are subject to change.

Interactive Road Closure Map

This interactive map outlines the road closures, highlights alternate routes and provides access information for popular destinations which will be affected by road closures during the race.

Google Maps does NOT take into account the road closures on race day.
