Seems like it could and should be bigger than 175. I've never done the event, so I can't say for sure--I'll have to trust the judgment of people who have. But, if you went from 175 x 2 = 350 riders the last several years to say 200 x 2 = 400 or 250 x 2 = 500 riders this year, and not straight to 800, then it should be manageable. I'd sign up as a volunteer this year if they increase it above 175. I'll hand out water bottles, pickup trash or whatever. I plan on signing up next year and don't want to have the same experience as when I tried reserving a cottage at Crystal Cove--ever try that? Sounds like even harder than signing up for VQ/CC... Mountain Biking is growing in OC and elsewhere, including high school leagues, etc. So too should the allowed participation in this event. Just my humble opinion and hope.
