Terrain is generally rolling, with some short steep sections, but there are no long, grinding killer hills. Hot weather can make this trip far more grueling. The pickup truck carries all the food, water, and gear. You'll carry only a light day pack or small pannier. All meals are prepared for you, but you'll be responsible for putting up and taking down your own tent, and washing your dishes.
Outfitters typically provide full mechanical support-spare tires, parts, and such.
The weather is highly changeable, especially in the fall. Temperatures can range from blistering to bone-chilling. Rain and high winds are possible. A serious mishap would require a long, slow, bouncy evacuation. Saddle sores are a common malady of the unprepared.
