Mario Kart Wii Speedrunner Shatters Limits with “Humanly Impossible” Superslide Glitch

When Human Skill Beats the Bots: Ejay B’s Jaw-Dropping Mario Kart Wii Record

As someone who’s watched Mario Kart Wii’s speedrun scene for years, I never thought I’d see the day when a real player-hands, nerves, and all-would pull off the so-called “Superslide” glitch. For ages, this trick was the stuff of TAS (Tool-Assisted Speedrun) legend: the robotic, frame-perfect runs where a computer inputs inhumanly precise commands. So hearing that speedrunner Ejay B managed to nail this technique and crush the world record left my jaw on the floor. This isn’t just another micro-optimised lap-this is human achievement redefining what’s possible, not just for Mario Kart Wii, but for speedrunning culture as a whole.

• This wasn’t “just” a new world record; it was a human demolition of boundaries set by computers.
• Ejay B spent 3000 attempts to land the trick—a testament to obsession and skill.
• The run challenges the barrier between human runs and tool-assisted wizardry in speedrunning.
• For Mario Kart Wii, a speedrun formerly ruled by consistent routing now faces a future of bold risk-taking.

Why This Glitch Was Supposed to Be Impossible

Let’s not undersell what happened here. In the Mario Kart Wii speedrunning world, there’s always been a clear line: what humans can do, and what only TAS (with frame-perfect program input) can accomplish. The Superslide—where you hit a precise angle and manipulate game physics to catapult Mario unreal distances—was always on the latter side. For years, TAS videos would show otherworldly warp launches, with most human runners resigned to just watching and dreaming. The community consensus? Humans weren’t precise enough to thread the timing needle—until now.

3000 Attempts and a One-in-a-Million Lap

Here’s what makes this story wild: unlike a typical world record chase, which involves shaving milliseconds off with tight lines, this record required relentless, mind-numbing attempts at something that, statistically, shouldn’t work for a person. Ejay B’s choice of Circuit Mario (the bland first track of the game) wasn’t about style points—it was about hunting the precise geometry and frame timing needed. After 3000 tries (seriously, who even counts anymore after 500?), he lands the glitch: launching himself into the track itself, bypassing sections of the course, and clocking a 21.212 second lap that redefined the leaderboard in a single, absurd leap.

Breaking Down the Superslide: Human vs. TAS

If you’re not familiar with speedrunning jargon: TAS runs are where a computer plays the game, inputting perfect commands—no human can match those inputs… until now, apparently. Human runs are about doing the “possible,” while TAS explores theoretical limits. Often, techniques discovered by TAS leak into real runs only years down the line—if ever. Superslide was one of those]. Even as techniques get friendlier, this one became a meme for “never gonna happen in a live run.” Until this week, when Ejay B—through sheer grind—proved the meme wrong. That’s what makes this so exciting for anyone who has ever tried to break a game themselves: it’s a modern Icarus story, only this one landed and stuck the trick instead of crashing into the digital sun.

Why It Matters: The Future of Mario Kart and Speedrunning Culture

This isn’t just a tale of digital dexterity—it’s a moment that could change how speedrunners think about “impossible” strats. Will more tools tricks cross the digital divide with enough patience? Is the measurement for human achievement just about to move again? This run also blows open the usually conservative culture around Mario Kart Wii speedruns. For years, the fastest runs stuck to reliable, everyman routes. What happens when the bar for a top lap is something most humans still can’t repeat outside of a miracle session? Do other runners spend their lives chasing the next computer-level trick, or will the scene split between ultra-glitch and “pure” categories?

TL;DR

Ejay B’s new Mario Kart Wii lap record isn’t just a number—it’s a shot across the bow for how we think about human limits in gaming. The lines between TAS and human achievement just got a little blurrier. For speedrunners and Mario Kart fans alike, the impossible is suddenly starting to look possible—and the grind just got realer than ever.
