As mentioned in another thread, I am planning a West-East Coast ride in July. Has anybody done the ride from Prescott up to Flagstaff? It appears that there is about 25 miles of with some good climbing, 15 miles of good downhill and then 54 miles of climbing with 4000 feet of elevation gain. July temperatures don't look overly extreme from Prescott to Flagstaff. Looks like a very challenging stretch.
