On day 17, I rode 24.7 miles across Nevada. Starting on the Pony Express Trail northeast of the Grubbs Well Pony Express Station (N39 37 24.8 W116 28 33.4), the ride continued northeast pass the Roberts Creek Station (N39 45 00.8 W116 17 05.2) and ended just pass the Sulphur Springs Station (N39 37 24.8 W116 28 33.4). The ride included a steep section where the grade topped 17.5%; this is the steepest incline that I have faced so far. Crossing Highway 278, I got a short view of the terrain in street view on Google Maps [see second figure below].
