On day three, I rode 24.82 miles from Rescue to Pollack Pines. From Green Valley Road, I rode through downtown Placerville and then out Carson Road past the entrance to the Apple Mountain Golf Course to Camino. I headed east along the Pony Express Trail from Camino to Pollock Pines and ended up on Highway 50 east of Pollock Pines. There were several short sections where the grade got to 12.5%.
One interesting observation is that the software will not let you ride on the freeway.
