I might actually go for the Mt. Hamilton Challenge next year. I was hoping to do it this year but my training/motivation took a nosedive around then. 
Now that I've ridden my permanent route twice, which has about the same distance & nearly as much climbing as the MHC (altho the climbing on my perm is more spread out), I'm much more confident I could tackle the MHC.
Apart from that, I'll need to complete a 200K+ brevet or permanent in each of the first 7 months of 2009 if I want to earn a RUSA R12, so I'll probably do some of the local 200K brevets this spring. A 300K, I don't know, we shall see.
Oh, and I have a plan brewing to get a team together for the Fleche on easter weekend.
