At two blocks long, LA's Fargo St hill is pretty short. At a 33% grade, however, it's also pretty painful to ride up. The LA Wheelmen, a cycling club, sponsor an annual Fargo climb where the goal is not only to get up Fargo St, but to do it as many times as possible. Within a time limit, you ask? No - just until you can't ride anymore because you're throwing up and/or dead. Some photos from this year's event -
