1 day from Virginia to Maine will be a stretch. The traffic that you are going to hit in cities such as DC, Baltimore, Philly, NY, and Boston will make that 14 hour time much longer than it appears. The google maps times that they give you also does not include stops for gas, sightseeing, food, etc. You should probably add 3 - 4 hours minimum to the 14 for all of the stops.
