For all that it's pretty short, this one always hurts. It also goes on longer than you think it will. It starts out very steep, and once you get over the steepest part, you realize that it's not as short as it looked, but neither does it ease up enough to let your recover. It's very easy to go out too hard on this one when trying to sprint to the top.
