The race course was BEAUTIFUL. We drove it the day before so we knew what to expect, and I HIGHLY recommend this to people. The course, because of the turns and grade of descent, makes you run on a slant for a good portion of the race. Miles 1-5 are completely downhill, but when you reach mile 5 you have a slight hill followed by flat. You go a little further and I think it's around 7 when you find a small hill, but then it's downhill until you turn off of Squaw Pass road. Miles 1-11 are a significant descent for you to use to your advantage. You won't feel tired, but you should fuel adequately so you can finish the race. Mile 11-16 you face some large, rolling hills that honestly went by quickly. I played the climbs conservatively and then used the large drops to my advantage at the top of these hills. At 16 you start a flat race until mile 20. This was where I hit the wall and thought it was toughest because of the flatness. Shortly after mile 20 you reach your last hill. From there, you flatten out or descend again. The last two miles are purely downhill with exception of the .1 of a hill to finish, but then you actually finish running down to the finish line with your last 500 feet or so. I didn't notice any elevation problems either, but I think that's because I got in on Friday and was able to acclimate a little bit.
