In the Contra Costa Times "Timeout Weekend" section today, there was a full-page ad for the TOC. The copy read "America's Greatest Race.. Free Spectator Event...Mt Diablo". It also said "Arrive by noon - limited parking - roads close at 2:00 PM".
Now I'm assuming the part about "arrive by noon" and "roads close at 2:00 PM" was intended for those planning to DRIVE to the event. Further, I'm assuming the roads will NEVER close to cyclists and pedestrians, except of course when the riders get close and the CHP and other support vehicles encourage you to get the heck off the road and outta their way. However, I could find nothing on the TOC website that confirmed my assumption.
Does anyone know anything about road closures on Diablo and who exactly is affected by those closures?
