The Devil Mountain Double Century is a very difficult double century over the mountains and hills bordering Silicon Valley, including Mount Diablo and Mount Hamilton.

The ride starts in San Ramon, and after some rolling hills, leads up Mount Diablo. The top of the climb is known as "the wall".

After the descent and more rolling hills, the route leads up Morgan Territory. From here it descends towards an area of big hills covered in wind turbines, before leading over Altamont Pass and Patterson Pass.

Mines Road leads up the backside of Mount Hamilton, at an altitude of 4,360 feet the highest point of the ride.

The descent leads into San Jose. After a few urban miles, the route climbs Sierra Road (10 percent average grade for three and a half miles).

The descent leads into Sunol. The route then climbs Palomares Road and Norris Canyon, with a downhill finish into San Ramon.
