Thanks for all of the advice! I think the hardest thing will be finding something to keep my feet warm and yet still be able to use my road shoes. Luckily my shoes are probably a half size larger than they should be which allows me to wear multiple sock layers without coming close to cutting off circulation. I do not like the idea of going back to platforms as I think that it would detract from my training, but if that is what has to be done to keep me warm and riding then it may be what I end up doing. I will make sure to pick up one more head layer as well. Another problem I think I may have run into is that I did not eat enough before leaving and about 25 miles into the ride I started to feel really weak, dizzy, and that is when I got really cold. I have done this in the summer where you start feeling clammy even when it is hot out. Maybe this added to the level of frozen I was feeling.
