Westerndh's post got me thinking about the 400 mile challenge again. Which route is the best for the challenge. I was thinking someplace with a high starting altitude, long descent, nice long flat run out for the finish. I picked Frisco, CO to McCook, NE (Frisco, CO to McCook, NE - Google Maps). One would burn some battery getting up to the Loveland Pass, but you would have space in the battery to regen all the way down to Denver (plus it's a fast run and can tick of miles fast). Then spin around Denver and head out to Nebraska (picking a day with the prevailing winds are blowing east). Trouble is you find yourself in the middle NO WHERE Nebraska if when you finish and worse if you fail... Maybe Tahoe down to Sacramento down the central valley in California?
