Noob report
This is my first week commuting. I caught the bug and bought an Uptown 8 last week. I switched to layers after trying to wear work clothes the first two times. So, I'm gradually learning how to get comfortable. My best learning is to pace myself and not push the hills. It took the same 35 minutes today without standing and I arrived fresh as can be. It's 32 degrees in St. Louis and I think I can remove a layer and still be comfortable.
