 Think of Sunny Jim as more like Sonny Liston. On the climb, Jim is going to hit you hard right away, let you hang on the ropes a little bit, and then go for a middle to late round knockout. What this climb lacks in length, it makes up for in gradient. If you like a quick shot of pain, this is your trail.
