Regarding the sometimes muddy conditions on the C & O, especially when approaching a puddle, I have found it best to just ride through the puddle. The mud on either side is often turned to slippery slush and a wipe-out can happen. You may get a little dirty, but the Potomac is right there to scoop up in your hands and clean up. As for bikes, either a mountain bike or hybrid is my choice--never a road bike. Beautiful as the trail is, it has some rocks and roots here and there. Nothing to worry about.
