Long jump
A long jump is a type of jump that spans a long distance while remaining close to the ground. Long jumping is performed by pressing the crouch button followed by the jump button while moving. Although long jumps are not the most powerful method of gaining distance in Super Mario Odyssey, they are often convenient due to being very quick to execute.
Execution
A long jump can be executed in two ways. The first method involves getting a running start, and then pressing the crouch button followed by the jump button. This is the same button sequence as a backflip, meaning the only thing that differentiates the two is whether or not Mario is moving. The second way of initiating a long jump is pressing the jump button while Mario is rolling.
Properties
Long jumps have a height of only 144 units[1], making them one of the shortest types of jumps. This sometimes makes them useful for clearing a low ceiling.
One of the defining properties of long jumps is that they begin with a fixed speed. This makes them a good way to accelerate quickly if Mario is not moving prior to the long jump. However, this speed is not particularly fast compared with some of the fastest methods of movement such as rolling, meaning it is not particularly useful for crossing long distances in speedruns. Long jumps are perhaps better suited for gaining speed within a small space.
