There are two routings for the Day 6 biking. This is the shortest but more dangerous of the two. Rather than use back roads to avoid I-80, it uses the highway itself – not a great idea. The first 27 miles are fairly flat, however, that is followed by two considerable ascents – one of 1,500 feet followed a few miles later by a 1,000 ascent. The last five miles are flat. If you follow this itinerary, you do so at your own risk. Failure to exercise good judgment can result in traffic violation citations, injury and even death. If in doubt, please consult with state and local law enforcement agencies.by fbrusca
