Hey Jo552006, first of all, how exciting for you to be taking on this challenge, and with plenty of time to get you and your gear in shape, so you can really enjoy the ride. I've done tons of long distance cycling, and I agree with those who suggest that fit of your bike is REALLY important. I also suggest a second hand Cannondale or Trek touring bike - probably a couple hundred, at most. I still happily ride my 25+ year old Cannondale tourer for long and mountainous several day rides (I'm in Pa). As for saddle, less big and less cushy is best -- I suggest a Brooks leather saddle, I have a B19 on a couple of my bikes, and I love them. Finally, don't be put off by riding in the cold -- it gets cold in my part of Pennsylvania, too, but I love winter riding. And I'm bored to tears by indoor trainer riding, so I end up skipping it all together. Layer up, pay special attention to keeping your hands and feet warm, consider a spiked front tire for snowy, icy roads (you can find on line instructions for making one of your own, cheap and reliable), and go at it. Enjoy!!
