That's really tempting -- art is such a great bribe to dangle too, not to mention an event where everyone's joining up together. If it wasn't for the length, I'd be inclined to sign up; the length alone doesn't bother me, I'm just not sure when I'd be able to fit 20k-40k reliably on top of everything else going on. :/ Though the advance notice of when during the year it might be helps a lot.
