It appears to be based from the Ledge Jump.
This obstacle proved to be immensely difficult as it took out several competitors like Ryan Stratis, the "Brazi Bros" (Alexio Gomes and Lucas Gomes), and Reko Rivera. A total of ten competitors failed the obstacle, typically due to struggling on the reach on the first cube or making a leap transition to the second cube.
An interesting completion of this obstacle occurred during Daytona Beach finals, when Jessie Graff used an unorthodox way of making the transition to the second cube. Instead of making a leap to the second cube, she was doing the split, by putting her left foot on the second cube, while her right foot was propped to the first cube, in order to make an easier transition, and making her completed the obstacle and going all the way to the Elevator Climb. Later that night, Travis Rosen also tried her method on the transition and successfully completed this obstacle and going all the way to the Circuit Board. While on the other hand, Drew Drechsel tried her method on the transition, but failed to make it, despite being nearly the same height. Fortunately, he instead used the traditional method of transition from one cube to another, and cleared the obstacle, along with the course altogether.According to ninja veteran Daniel Gil on NBC's Crashing the Course, it is recommended for competitors to visualize or strategize with the obstacle, such as the open ledges, to ensure competitors smoothly transition in addition to conserving energy.
