Jacksonville area races.

Hi Floridians.  I have been asked to make arrangements to come to Jacksonville next year and do a talk to several groups about organ donation and awareness, with a pretty open schedule.  My best friend works at the Omni in Jacksonville, so I like to be there anyway, and I am fairly familiar with the area.  I would like to combine this trip (since someone else is paying the travel expenses) with a race.  I can speak to the groups, then tell them about the race and puntuate the message by inviting them to come and see me race and being able to see what the donation of organs brings to the table in healing possibilities.

So ----- What race should I do?  The month of June is out for me, as I am supremely busy, but I am pretty open from March to November 2009.  Just looking around, I saw that Jacksonville has a 3 race set on Little Talbot Island (which I have never been to) and St. Augustine has a 3 race set at Marineworld.  What are the best races in the area?  Does anyone have any experience with any of these races?

Thanks for any help you can give me, and please, sign up as an organ donor and let your family know about your decision.
