The city of Santa Clarita will host the 2018 Santa Clarita Marathon, presented by Parkway Motorcars, this Saturday and Sunday, Nov. 3 and 4, and has listed street closures planned for the event.

The public can expect minor delays and rolling road and parking lot closures periodically both days to accommodate the races. Detours will be provided for major road closures and residents are asked to plan ahead to avoid delays.

The majority of Santa Clarita Marathon events will take place on city multi-use trails to reduce the number of street closures, including West River Trail, South Fork Trail, Chuck Pontius Commuter-Rail Trail, Valencia Paseos and San Francisquito Trail.

Residents are encouraged to adjust their trail usage until after the conclusion of all events to avoid interfering with runners on the course.
