Learn from the most epic speedrun failures in gaming history and discover strategies to avoid similar mistakes
Introduction: When Speedrunning Goes Wrong
Speedrunning represents one of gaming’s most demanding disciplines, blending technical mastery with intense pressure. The pursuit of perfect execution often leads to spectacular failures that become legendary within the community.
Competitive speedrunning demands hundreds of hours of dedicated practice, precise execution, and mental fortitude. When everything aligns, records fall—but when things go wrong, the results can be both heartbreaking and educational.
Public speedrun failures create unforgettable moments that spread rapidly across gaming communities. These incidents highlight the razor-thin margins between success and disaster in high-stakes gaming environments. While embarrassing in the moment, they provide valuable lessons about preparation, adaptability, and human error.
The pressure of performing before thousands of live viewers amplifies every mistake, transforming minor errors into career-defining moments. Yet these public failures often receive overwhelming community support, demonstrating the positive culture that surrounds competitive gaming.
We’ve compiled seven of the most instructive speedrun disasters from major events, each offering unique insights into what can go wrong and how to prevent similar catastrophes in your own runs.
1. The Pacifist Who Couldn’t Stop Killing
At SDGQ 2016, speedrunner Kythol faced an unusual challenge during his Ty the Tasmanian Tiger pacifist run. The category required completing the game without defeating any enemies, a restriction that viewers had specifically requested through donation incentives.
Despite his intentions, Kythol began eliminating opponents within minutes of starting. He repeatedly apologized as he continued dispatching optional enemies that could have been easily avoided. The cognitive dissonance became palpable when he commented about mastering pacifist techniques, only to immediately violate the run’s core rule moments later.
This incident highlights the challenge of breaking deeply ingrained gaming habits. Pacifist runs require completely rewiring your approach to game mechanics you’ve practiced for hundreds of hours. Professional speedrunners now recommend specific mental preparation techniques for category shifts, including visualization exercises and creating explicit rule reminders displayed during runs.
Common pacifist run mistakes include automatic combat responses, failure to plan alternative routes around enemies, and underestimating the mental adjustment required. Successful pacifist runners practice avoidance strategies as diligently as they practice combat techniques.
2. When Technology Betrays: The 3DS Battery Crisis

Battery failure represents every handheld gamer’s nightmare, but for New Super Mario Bros. 2 speedrunner EeveeSpirit, this fear became reality at the worst possible moment. Twenty-four minutes into an estimated 31-minute run, the unthinkable occurred as his 3DS abruptly died.
The clip captures EeveeSpirit’s initial confusion transforming into horrified realization as he understood what had happened. When organizers suggested simply plugging in the device, his devastating response—”I don’t have a charger!”—cemented this as one of speedrunning’s most preventable disasters.
This failure spawned new standards for hardware preparation in competitive speedrunning. Professionals now recommend multiple preventative measures: always fully charge devices before events, bring backup power banks, test battery health beforehand, and have charging cables readily accessible. Some runners even bring secondary devices as emergency backups.
Modern speedrun events often include mandatory equipment checks to prevent similar incidents, verifying that all handheld devices meet minimum charge requirements and that runners have necessary accessories available.
3. The Halo Run That Exposed a Cheater
Halo speedrunner Cody Miller’s AGDQ 2011 performance became legendary for all the wrong reasons. His Legendary difficulty run of Halo: Combat Evolved was projected to complete in two hours but stretched to double that timeframe, requiring two separate difficulty reductions along the way.
The disastrous performance raised immediate suspicions within the community. Subsequent investigation revealed Miller had been submitting spliced runs from home—carefully edited composites of multiple attempts presented as single continuous runs. This practice left him completely unprepared for the demands of live execution.
This incident exposed the critical difference between curated performance and live execution. Run splicing creates artificial results that don’t reflect true skill or consistency. The community response established stricter verification standards for major events, including more rigorous proof requirements and increased scrutiny of suspicious performances.
Modern speedrunning emphasizes transparency and verification. Top runners now document their practice routines extensively and participate in community verification processes. The Miller incident serves as a permanent cautionary tale about the importance of authentic achievement in competitive gaming.
4. Zelda 2: When One Death Ends It All
Zelda speedrunner Pro_JN’s ADGQ 2015 attempt demonstrated how quickly mental factors can derail technical performance. Just twelve minutes into his estimated eighty-minute Zelda 2 run, an unexpected enemy attack from off-screen ended his initial attempt.
The critical failure occurred during his restart attempt when he couldn’t replicate a essential sequence-breaking glitch. This particular skip allowed bypassing significant portions of the game, and without it, his time estimates became impossible. Despite being early in the overall run, Pro_JN made the difficult decision to abandon the attempt entirely.
This scenario highlights the psychological challenges of recovery in speedrunning. When key strategies fail early, runners must decide whether to continue with compromised routes or reset entirely. Mental resilience becomes as important as technical skill in these moments.
Professional runners now develop contingency plans for when primary strategies fail. This includes practicing backup routes, learning recovery techniques, and mental preparation for continuing despite setbacks. The ability to adapt mid-run separates elite performers from those who crumble under pressure.
5. Mario Kart’s Most Embarrassing Finish
Drog’s AGDQ 2015 Mario Kart Wii Any% run deteriorated into a masterclass in compounding errors. His performance accumulated small mistakes throughout earlier races, but reached its climax during the Coconut Mall segment where execution completely unraveled.
The critical failure involved an out-of-bounds glitch that required precise positioning and timing. Drog attempted the sequence six consecutive times without success, finally executing correctly on the seventh attempt. By this point, the entire CPU roster had crossed the finish line, leaving him in eleventh place—an embarrassing result for a speedrun focused on winning races as quickly as possible.
This incident demonstrates the danger of fixating on difficult techniques when simpler alternatives exist. Professional racers now emphasize risk assessment during runs—knowing when to abandon high-difficulty strategies that aren’t executing consistently.
Advanced Mario Kart speedrunners practice multiple approaches to each technical section, allowing them to switch strategies when primary methods fail. They also develop better error recovery techniques to minimize time loss when glitches don’t execute as planned.
6. Final Fantasy’s Double Counting Catastrophe
Gyre’s AGDQ 2016 Final Fantasy run showcased how precise counting becomes critical in glitch exploitation. His strategy relied on the staircase glitch—a technique involving repeated screen transitions between two connected areas via stairs to manipulate game code.
This manipulation allowed skipping directly to the game’s final segments, but required exact execution counts. Gyre’s first attempt failed due to a counting error, prompting a complete restart. Incredibly, his second attempt replicated the same counting mistake, forcing him to abandon the run entirely.
The double failure highlights the cognitive challenges of maintaining precise counts under pressure. Modern speedrunners have developed numerous techniques to prevent similar errors, including audible counting, visual counters, and breaking long sequences into smaller, more manageable segments.
Professional glitch runners now practice counting techniques as fundamental skills. Some use physical counters or software aids during practice to develop muscle memory, while others create mnemonic devices to track complex sequences. The key is developing counting methods that remain reliable even under intense pressure.
7. The Save File That Vanished
Divinity: Original Sin 2 speedrunner Semanari experienced every gamer’s nightmare at AGDQ 2019 when critical save files disappeared during his run. His strategy depended on retrieving a specific quick save from earlier in the session, but excessive saving created confusion about which file contained his progress.
In a moment of panic, Semanari accidentally overwrote the essential save, eliminating his ability to continue the planned route. His attempts to recover and catch up proved futile, leading to an early run termination despite significant preparation.
This incident revolutionized how speedrunners manage save files during complex RPG runs. Professionals now develop strict save naming conventions, create backup copies at critical junctures, and practice file management as part of their routine preparation.
Modern save-dependent runs often include specific file management protocols: limiting total save counts, using descriptive names with timestamps, and creating safety backups before major events. Some runners even practice recovery scenarios to prepare for potential file management errors.
The community’s supportive response to Semanari’s misfortune demonstrated the positive culture surrounding speedrunning, with many offering encouragement and sharing their own file management strategies to prevent future incidents.
Learning From Failure: Speedrunning Wisdom
These seven catastrophic failures provide more than entertainment—they offer masterclasses in what separates successful speedruns from disastrous ones. Each incident reveals critical aspects of preparation, execution, and recovery that every competitive gamer should understand.
The common threads connecting these failures include inadequate contingency planning, poor hardware management, insufficient mental preparation, and underestimating the pressure of live performance. Addressing these areas can dramatically improve your success rate in competitive gaming.
