Thanks for everyone's support! I plan on increasing my long ride every weekend, so I think this is doable. There are great traing rides for my metric century in May with a local bike club. I have started working on hills, and have a plan to go to the big hills in New Jersely in June. I am even thinking of going up to Massachusetts in July to practice on the actual hills.

I think the advice not to get too carried away in the beginning is excellent, because I have exactly the kind of personality that will do that, how did you know?!

Plus I have lots of support from PMC and friends -- and from the folks on TE that I don't even know. How cool is that!
