It sounds like fun. If you are near a lake, you can probably avoid the monster climbs, but that isn't easy in NH. The last time we were up near Mt. Washington, I got a book out of the library to look for rides before we left. I chose the one that was called a "ramble," i.e. did not entail climbing the Kangamangus Hwy. Well, it was short (28 miles), but there was about 3200 feet of climbing.
The weather should be great.
