That said, it's also been a rewarding week. Each of the drivers and riders will have booked four solid days of practice runs on the course, and we've come away with hundreds of photos from what is undoubtedly the most scenic venue in motorsports.
With all of the qualifying runs complete, the running order has also been set for the 100th anniversary of the Race to the Clouds. Romain Dumas turned in the top time in qualifying and will therefore get a coveted early start time just behind the motorcycle and quad classes. That might not seem like a big deal, but for Dumas it surely will be. He barely lost out on the overall win in 2012 when inclement weather later in the day slowed his race, while Rhys Millen was able to complete the course on dry pavement. Dumas will need all the help he can get, as he qualified a mere two seconds ahead of Millen. Both will also have to watch out for the Acura NSX 4-Motor EV Concept driven by Tetsuya Yamano, who was less than seven seconds behind Millen.
