The '''Backwards Long Jump''' (or '''BLJ''' for short) is one of the most versatile hyperspeed methods, done by long jumping backwards. It is the result of a minor oversight by the game's programmers/developers: There is no reasonable limit on Mario's speed when it becomes negative during a long jump.

It is the result of a minor oversight by the game's programmers/developers: There is no reasonable limit on Mario's speed when it becomes negative during a long jump. Therefore, by long jumping backwards in a position where you can continue to long jump backwards every few frames, you can achieve negative hyperspeed. BLJs can be done on certain slopes, stairways, and obstacles. To perform a BLJ, do a long jump with Mario facing away from the obstacle/stairway/slope but move backwards towards it (by holding the joystick in the opposite direction). Mario will collide with the obstacle/stairway/slope, leaving him on the ground and enabling him to backwards long jump again. Mario's speed becomes negative at this point, and BLJing repeatedly causes a negative speed increase of approximately 45-50% of Mario's currently stored speed at that time. Once the desired speed is reached, simply stop BLJing and Mario will zoom off backwards at an incredibly high speed. If you continue BLJing long enough, Mario's speed, stored in a float, will eventually reach -229399772256808620000000000000000000000, then tick over to -1.#INF, and crash the game. | ||
The key aspect of BLJs is Mario's capability of retaining negative speed temporarily. Eventually, the speed will increase back to 0; however, there are a few frames within a BLJ in which his speed doesn't deplete instantly. These frames allow for repeated BLJs, thus increasing his speed. | The key aspect of BLJs is Mario's capability of retaining negative speed temporarily.

Stair BLJs were the first kind of BLJs to be discovered. A Stair BLJ consists of long jumping backwards onto stairs, which are basically tiny floors, which Mario can run directly over.

BLJing on stairs works similar to Elevator BLJs because they both consist of Mario's jumps being interrupted allowing for more jumps to be performed, however the timing must be precise. | ||
Here's how they work: With a precisely timed BLJ, Mario's vertical position snaps to the next highest stair, ultimately reducing Mario's vertical speed to 0 (allowing him to repeatedly BLJ on the ground). When this occurs, his negative horizontal speed is temporarily stored, allowing him to repeat the process which results in a greater amount of negative speed. | Here's how they work: With a precisely timed BLJ, Mario's vertical position snaps to the next highest stair, ultimately reducing Mario's vertical speed to 0 (allowing him to repeatedly BLJ on the ground).

Here's how it works: When BLJing on a steep slope, Mario's jump is interrupted by the steep ground. With no negative horizontal velocity, Mario's long jumps behave just as the developers intended. However, on steeper slopes, with a negative horizontal velocity, and with ground located behind Mario, the game has no choice but to force Mario's position backwards along with an increased vertical position. This process is repeatable, allowing for Slope BLJs to be performed. | Here's how it works: When BLJing on a steep slope, Mario's jump is interrupted by the steep ground.

Here's how they work: BLJs are possible on rising elevators because an elevator's vertical velocity allows them to catch up to Mario as soon as he leaves the ground from a BLJ. This interrupts the first jump and allows him to jump again, thus repeating the process of a BLJ. | Here's how they work: BLJs are possible on rising elevators because an elevator's vertical velocity allows them to catch up to Mario as soon as he leaves the ground from a BLJ.

Elevators that move in a horizontal fashion, such as the ones located in the volcano of Lethal Lava Land, do not have the properties to initiate Elevator BLJs because they do not have enough vertical velocity. | ||

These are probably the trickiest locations to find because some of them are invisible or are just plain easy to overlook. However, walls above a floor can also act like ceilings.

The most common Low Ceiling BLJ is the one presented in the video (located in the Jolly Roger Bay room). Both of the Lobby BLJs in the main room of the castle are also Low Ceiling BLJs, but they utilize Invisible Wall Hitboxes which act as Low Ceilings. | |||
