Humongous Halloween Uni climb in San Pedro this morning, 10.31.12. This one rivals Fargo for sheer steepness, but it's a narrow walkway so there's no way to "zig zag", and must be ridden straight up! I measured the distance by gps at about 250 feet, with elevation gain at a whopping 102 feet! According to this calculator, that translates to a massive 41% grade!
I'm pretty sure the walkway is less than that, but it sure felt at least as steep as Fargo's 33% grade, even though this walkway is half that distance. Whatever the actual number is, it's a steep mutha, and a GREAT training hill!
The last time I was there and tried it, I failed less than halfway up as I lost momentum and stalled. This morning I went back but with the same light weight road tire I used for my Fargo climb. I had just filmed my first attempt using my tripod, which couldn't capture the whole climb. I was just about to leave when local came along and offered to film me, and followed me all the way up!
I'm sure this could also be done on a bike, and makes a fantastic training climb!
