If you’re driving to Caltech, it’s best to park in one of the parking structures on campus (see map) -- DO NOT PARK ON THE STREET! (if you're staying past midnight) Otherwise, you will get ticketed at 2AM. The Caltech parking structures are free to park in for the entire marathon. The nominal address for Caltech is 1200 E California Blvd, which will take you to the southern edge of Caltech, and from there you can follow the map below. It’s about a 5 min walk from the parking structure to Dabney Hall.
