Our path through the Santa Cruz Mountains has a about a 3 mile stretch through a trail that is gravel. I've ridden this on my road bike (23 tires) several times. I guess I have been mountain biking too much and expect my road bike to perform like a mountain bike. It does not exactly, but it is not as scary as I originally thought it would be. If it's a short stint, I say try it.
