Over the Hills to North Plains (and Pumpkin Ridge)
Start at the upper parking lot of REI at the Streets of Tanasbourne, Hillsboro. Plan to add 10 miles to the attached map/cue sheet and ride to where the pavement ends on Pumpkin Ridge Road. The ascent on Pumpkin Ridge averages about 3 percent, with a few steeper pitches. Enjoy the hills on Helvetia, Jackson Quarry and Mason Hill roads before the ascent and descent of Pumpkin Ridge. Refreshments in North Plains, leaving 17 miles of flat roads to the finish.
