Over the Hills to North Plains via Pumpkin Ridge
Start at the upper parking lot of REI at the Streets of Tanasbourne, Hillsboro. Climb the 7.5 miles from the right turn off of Shadybrook to the top of Pumpkin Ridge Road, where the pavement ends. The ascent averages about 3 percent, with a few steeper pitches. Enjoy the hills on Helvetia, Jackson Quarry and Mason Hills as a warm-up to Pumpkin Ridge. Refreshments in North Plains, leaving 16 miles of flats to the finish. Plan on 16-18 mph on the flats.
