If it doesn't bother you, you might want to consider the following event organized by the DSE Runners, a local running club in San Francisco:
6-Hour Distance Classic
Crissy Field, San Francisco, CA
Date: July 10, 2011
The course is flat. I believe it is a 1.061 mile loop going around a lagoon.
There will be 1 fully stocked aid station with water, electrolyte drink and snacks.
I really, really dig the price. Currently, it's $10, not including the pesky Active.com fee.
If it is not too foggy, you will also get a very nice view of the Golden Gate Bridge.
