A mixed gravel century (almost a century) that includes the Crooked River Canyon scenic bikeway, the Maury Mountains, and the Post / Paulina road. The ride links two of the best paved roads in Central Oregon with a gravel segment through ranching and farming country and some national forest.
The first paved sector is from downtown Prineville out the Crooked River Canyon to the top of the grade above Prineville Reservoir and down the other side. The climb of the grade is a little over 4 miles and about 900 feet. The steepest pitches are at the start. The descent of the other side is a bit shorter and less steep.
At mile 28 the gravel begins. Ride through rolling farm and ranch country, up and over the Maury Mountains and down into Post. At Post, refuel at the General Store on milkshakes and meatloaf sandwiches. From mile 28 to mile 54 is uphill at 1 to 2% until the turn onto Kloochman Creek road, where the grade steepens to 5%. The descent into Post is 11 miles with a loss in elevation of 2000 feet. // Read More
From Post, it is paved until the finish, 27 more miles. Ride along the scenic Crooked River for a bit, climb some (900 feet over 4 miles), and then drop back down into Prineville.
One helpful hint for this ride. Start with your tires at a higher pressure, like 50 to 60 psi, at the gravel drop the pressure down to 20 to 30 psi, and back at the Post General Store air your tires back up to 50 to 60 psi.
The only aide station is at the Post General Store (mile 66). Also, there is very limited cell phone service along the route. You should plan on being
