The Backwards Long Jump hyperspeed method, or BLJ for short, is the most famous hyperspeed method in Super Mario 64. Due to their versatility, BLJs are commonly used in all kinds of speedruns and challenges.

When Mario initiates a long jump, his horizontal speed is multiplied by 3/2. A BLJ occurs when a backwards long jump is interrupted before the effects of drag can counteract the speed gain from the 3/2 multiplier. This does not occur with forwards long jumps because long jumps have a "hard cap" of +48 horizontal speed which Mario's speed cannot exceed. No such cap exists in the negative direction because normally the "soft cap" of -16 speed from drag is easily enough to stop any speed gain.

There are several different types of BLJs. The distinguishing feature of different types of BLJs is what they use to interrupt the long jump:

• Slope BLJs use slopes by going up the slope.
• Stair BLJs use stairs by going up the stairs.
• Side BLJs use two floors at slightly different levels by oscillating between them.
• Elevator BLJs use the upwards movement of an elevator or other object.
• Ceiling BLJs use an exposed ceiling or low-hanging ceiling by making Mario hit his head and start travelling downwards faster.

BLJs can also be pause buffered to increase the amount of long jumps that can be performed in a given amount of time or space.
