Gravel grinder ride to the top of Mt. Currahee. This is a hard ride with a lot of up-hill, and once you get to Mt. Currahee be prepared to hike the bike. It's a very steep road up. It at some points is as steep as 17%. If you can ride the whlole way you're a super stud. I was on my single speed with a 32/17 set-up.
