For anyone coming from Massachusetts, Portland is halfway there and is a great "pit stop". You can break up your ride, stop and get some delicious food or stop at any of their great breweries!
This is a brewery a few miles up the road that serves great local beer. They also have options for both breakfast and lunch. You can view their menu at: https://www.northernoutdoors.com/restaurant/
This is another option for breakfast or lunch. This is a quaint local inn with a beautiful view of the Kennebec River.
There are a few recreational options on site at the venue if you're feeling adventurous during the day on Saturday! You can find out any information needed right at the main lodge.
Take a light 1.7 mile (total) "hike" out to the beautiful Moxie Falls! It is a quick and flat trail. That leads you out to a beautiful waterfall. You can even bring your suit and take a dip in the falls!
