Racing frames are not ideal for converting into workaday commuter bikes. They will get you from point A to B, but come with inherent constraints due to the racing geometries. I have one bike that I use for commuting and it is a racing CX frame, again not ideal but it works for me for the short rides I take it on. For rides the length of yours, I would not want to do it unless I had a frame with much more relaxed geometry than that CX. Certainly not any of my racing frames.
