2012 Planning

I've got a list of Oly's I'd like to do next year and a couple Granfondo's (there's even a new one in May in Mission) but I'm trying to gauge how much is reasonable and how much is foolish.  So how soon after one Oly before I can do another?  I'm thinking of:

BareBones Duathlon May 12, Penticton

Wine Capitol of Canada Oly June 3rd, Oliver

VF Granfondo July 8, Penticton  (plus Kelowna the next weekend or Whistler in Sept)

Apple Olympic Aug 19, Kelowna

Volunteering for IM Canada (5 days in late Aug).

Stanley Park Oly Sept 3(?), Vancouver (or Cultus)

Kelowna Xterra Sept.

I do tend to overdo things so I'd appreciate opinions on how much time to allow for recovery or preparation for the next event.  I am just having fun with the planning.
