Got the hills covered! I live in NW Indiana, and although they aren't HUGE, they're big enough for me right now. There are a few inclines in the State park where I like to ride. some are steep, some are just long steady upgrades, but they are a workout. (at least for now). so I will take your advice, and do what I'm doing. short hard rides, followed by slower recovery, and throw in the 25 mile ride once/week. I might have to get a trainer though for the really cold months, or maybe just use that YMCA membership I have. They have a few exercise bikes, it's boring as it gets, but at least when the weather is too bad, I can fit it in. I do walking tapes at home when I can't ride, because it's easy to fit into my life, and adds variety.

Thanks for the advice! It helps when you know your on the right track!
