Rode the C&O into D.C. this past June. My experience was entirely different from a friend's, who rode the same route a couple years earlier. The trail is intended to be representative of the way it was when used as a mule path. That means rough, stones, roots, mud, loose gravel &c.
I was fortunate on my ride. The weather had been dry for a couple weeks. There was very little unavoidable mud, but lots of zig-zagging around remaining water/mud. There were lots of bumps and rocks to ride around. Poison ivy seemed to hang from every branch above the trail.
My friend's ride was all that plus unavoidable mud all over the place. He was a mess to see pictures of him on the ride.
That said it was great and I will be doing it again sometime soon, if not this coming summer.
Be sure your core is strong. I made mistake of riding GAP/C&O into D.C. in 5 days and focused training on just legs. I picked up a couple "souveniers" on trip: carpal tunnel from hours on handlebars and a crick in neck that hasn't stopped loving me, yet.
