This course goes to the 4 mile mark of Butterfield. It still has some good pitches, but stops short of the parts that are super steep and narrow and a little sketchy when the road is open to 2-way traffic. If you would like to skip Butterfield, it is a 14 mile ride. This is a C/D ride. You are welcome to come and ride faster on your own, but the ride leader will be riding a C/D pace and will ride with the C/D riders.
