Hi there - Just wondering if some of you may know how the Half Marathon weekend affects crowd size and so forth? We're planning on visiting California in early September 2011, and I noticed that the dates for this year are about the time we'd intend to be there next year. I have e-mailed the organisers to ask if they can advise me the 2011 dates - are they traditionally the first weekend of September? I am hoping that it will be 3/4 September as the tentative plan is to be at DLR for 10/11! Thanks so much!
