The Bike MS: Los Angeles charity ride will be passing through San Marino. Expect some traffic delays... 
The City of Pasadena is hosting their annual Multiple Sclerosis charity bike ride on Saturday March 23, 2019. The event starts at the Rose Bowl and travels throughout the San Gabriel Valley, including San Marino.
As stated above, part of the course passes through San Marino (see below for details). Between the hours of 10am and 4pm on Saturday, March 23, multiple bicycles will be passing through the City. The course is lined with three different colored arrows attached to poles. These arrows represent three different routes the riders can take which vary from 30, 55, and 100 miles in length. We are not expecting any major traffic delays as the riders will be spread out over a large area.
Below is the scheduled route through San Marino, starting on San Marino Avenue at the north city limit:
San Marino Avenue, south to Euston Road
Euston Road, west to Oxford Road
Oxford Road, south to Monterey Road
Monterey Road, west to El Molino Avenue
