I did the C&O trail with another 4 cyclists last year in August and it was very easy to do. Three of us had touring bikes, one had a mountain bike and I had a recumbent. I do believe though it could be messy following heavy rain as well as sticky for narrow tires.
On one stage of the trail three of us ran into multiple flats, turned out it was small bits of glass on the trail. It is somewhat tedious after a while with not much variation in scenery unless you get off and visit the small towns in the area but it certainly was easy cycling and kept us away from vehicles.
