South Gate Road climbs Mount Diablo from Danville, in Contra Costa County, California, USA, and this is the side the races take. Every October riders in the Mount Diablo Challenge race up it to the summit on closed roads; Nate English set the record of 43 min 33 s in 2008. The Tour of California climbed this side in 2012 and finished on the summit in 2013 and 2014.
This ride starts near the Athenian School, where the Challenge begins, and climbs through the South Gate and past the sandstone formations of Rock City to the junction. Summit Road then climbs to the top. In 2013 Leopold König went clear of Janier Acevedo 400 yards from the line to win, while Tejay van Garderen kept the lead; in 2014 Rohan Dennis won and Bradley Wiggins kept it. The ride ends beside the stone summit building, built by the Civilian Conservation Corps in 1939–42 from sandstone quarried in the park.
