Here are the medals for the San Francisco Marathon and the First Half Half Marathon that was held on July 29, 2012 in San Francisco, California.
The San Francisco Marathon has a full marathon and 2 half marathons on race day. The First Half runs the first half of the marathon course and includes the Golden Gate Bridge. The Second Half runs the second half of the course and does not go over the bridge. If you run San Francisco, you have to run the bridge!
