I have done DC to Pittsburgh in November ending up in Pittsburgh the Wednesday before Thanksgiving.
Weather can be unpredictable over 6 days riding. Most notably having to bike through fresh 1 inch of snow between Frostburg and Rockwood.
Restaurants and lodging options may be limited.
Yes the days are shorter, but if you start at dawn, you still have enough time to reach your next stop before dusk.
