Promoter: C4 Racing
Course Description: A point to point hill climb time trial from the North entrance of Mt. Diablo state park to the ranger house just below the junction.
Road Surface: Mostly good pavement.
Gearing: A 39×23 or 25 will probably be plenty. Most of the climbing is on moderate grades of around 5%-6% with one steeper pitch around half way.
Facilities: Porta Cans at registration and one at the start line.
Weather: In June it will be warm and possibly “Africa Hot”.
Rules Specific to this race: Of course there is no drafting in time trials.
Race Advice: Being familiar with the Mountain is a big plus. The first 1.5 miles is rolling and even has some fast, big chain ring sections. After that it gets harder… For a few years some of the guys in the pro/1/2 race used time trial bikes. That seems to have fallen out of favor and rightly so I think. The winning pro/1/2 rider averaged under 16mph.
For wheels I would go with the “aero trumps weight” philosophy. Something like a set of Zipp 404’s is the hot ticket. Some clip on aero bars might be beneficial for those first few miles also. Also wear your aero road helmet if you have one.
Lodging: Lodging is available in Walnut Creek or Concord.
