Essentially the same as the Quintuple Step, but with 5 intermediate platforms instead of 4. It was the first obstacle in the 16th, 17th, 19th-21st competitions. (The first obstacle in the 18th competition was the Rope Glider, but this proved to be too dangerous, thus the Sextuple Step was reprieved.)
