Climb up San Bruno Mountain from Downtown Brisbane, California - just south of San Francisco. This is a pretty steep climb of about 1300' in about 5 miles. It is very scenic from the top ( amid the radio towers - it is called radio road) and I panned my camera around at the end of the ride. This is a very popular ride for those wanting to torture themselves a bit and see who can do it the fastest - I am not one of those. Enjoy!
