Plutosmyfav, I'm sorry to hear you will probably not be able to make it!! Never say never, though!! Early January can be the absolute cheapest way to go to Florida-- really cheap rooms (a couple years ago, I got a $25 rate at the DD Hilton Concierge in early January!!), and really cheap flights-- maybe you'll be able to come down for a couple days just for the race!! There's still a whole year!
Alternatively, there are so many races all over-- maybe there will be a race closer to home, or somewhere the whole family would like to visit-- I have no kids, so I can't really have an opinion about missing school (and I was never allowed to miss school for a vacation), but I would think a couple days wouldn't hurt.
