The Dirty Vertical

Not really a mountain bike ride because it is ridden on dirt roads rather than trails, this 19 mile ride IS hilly, with some good stiff climbs and very fast descents. There is even a chance for food in Middlesex. A road bike with fat tires would work for this ride. There is an alternate version going the opposite direction and coming UP a hill that was originally a downhill which makes the ride a couple miles shorter.
