Here I listed some popular races around San Francisco Bay.
1. Napa Valley Marathon
March 2, 2008
2. Napa-to-Sonoma Wine Country Half Marathon
July 20, 2008

I registered this event this year, but I ran out of gas when I drove to the place.
So, I failed to show up. :(
One of my coworkers ran it and enjoyed the course so much.
I think I will join it in 2008.
3. Rock 'n' Roll Half Marathon in San Jose
October 14, 2007
Two of my coworkers ran it last year. There will be a lot rock'n'roll bands to cheer you up while you are running. I haven't ran this event, but it should be fun.
4. Big Sur International Marathon
April 27, 2008
5. Big Sur Half Marathon
November 11, 2007
Runners voted the most beautiful route in the U.S.A. You get to run along Highway 1 and see the spectacular scenery. The breeze from Pacific Ocean will cool you off.
6. Lake Tahoe Marathon and Half Marathon 7. Los Angeles Marathon
March 2, 2008
One of my coworkers joined it this year. He is highly recommended. You get the chance to run through all the diverse communities in the City of Los Angeles. He also mentioned that the big crowd will cheer you up along the course.
8. Disneyland Half Marathon
You get all Disney characters cheering you up along the course. It's wonderful for beginners. The tickets usually sell out soon, so you need to pay attention to the registration opening day.
9. Redwoods Marathon,Half Marathon & 5KThis race is amazing. It's on my list, too. You get the chance to run on the Avenue of Giants in Humboldt County. All those beautiful redwood trees will greet you with fresh air.

10. California International MarathonThis is the classic one. One of my colleague joined it. He highly recommends it. You probably will see more international elite runners in this event.
