I ride a rim brake bike on that trail all the time, and have for the past 14 years. What that post should tell you, is full coverage fenders are a good thing. I got tired of cleaning my wife's drivetrain every time we rode, so I installed full coverage fenders on her bike as well. Mine has had them since I bought the bike. I cannot imagine touring without full fenders, especially on the GAP and C&O trails.
