Turn onto Peak to Peak Highway at mile 14.7 and Brainard Lake Road at mil 19.4

Finish at Brainard Lake.

The roadway is in great shape and traffic fairly mild along this climb.  There is a 1 ½ mile gravel section after Jamestown just before Peak to Peak Highway, but it is manageable on a road bike, particularly with 28mm and above tires. From Jamestown, it’s ~4.5 miles paved and then ~1.5 unpaved to P2P. Unpaved not ideal on 23mm road tires.

2.1 miles of gravel/dirt at 1.5% beginning at mile 12.5 and continuing to Peak to Peak Hwy
