Most video games are designed to be explored at something close to a normal pace. You follow the story, learn the mechanics, fight enemies, solve puzzles and eventually reach the ending. A game that took developers years to create might take an ordinary player 20, 50 or even 100 hours to finish.

Speedrunners look at the same game and ask a completely different question: how fast can this possibly be done?

Speedrunning is the practice of completing a video game, or a specific objective within one, as quickly as possible. What sounds like simply “playing very fast” is actually a complicated combination of practice, planning, technical knowledge, precision and community research. At the highest level, players can spend hundreds or thousands of hours perfecting a run that may last only minutes.

The goal is not always to play the game exactly as its developers intended. Speedrunners are interested in understanding every rule the game follows and then finding the fastest possible route through those rules.

Every speedrun needs a clear set of rules

Before comparing times, players need to agree on what counts as completing the game. This is why speedrunning is divided into categories.

One of the most common is Any%, where the goal is generally to reach the required ending as quickly as possible without needing to complete everything along the way. Depending on the game’s rules, players may skip enormous sections of content to do this.

Another common category is 100%, which requires players to complete a defined set of objectives or collect everything required by that community’s rules. Games can also have categories built around completing specific levels, defeating certain bosses or avoiding particular techniques.

Different categories allow completely different styles of competition to exist within the same game. A record-breaking Any% run might last less than an hour, while a 100% run of the same game could take several hours.

Without standardized rules, comparing times would be meaningless. The category tells everyone exactly what challenge the runner is attempting.

Speedrunners memorize optimized routes

A serious speedrun is rarely improvised from beginning to end.

Players develop routes that specify where to go, which items to collect, which enemies to ignore and which actions to perform at particular moments. Every unnecessary movement potentially costs time.

Routes can become extraordinarily detailed.

A runner may know exactly where to jump, which direction to face and when to press a particular button. They may deliberately avoid collecting a useful item because the animation required to pick it up costs several seconds.

Even menus can be optimized. If selecting an item takes slightly less time from one menu position than another, competitive runners may organize their inventory around that difference.

Individually, these savings can seem absurdly small.

Across an entire run, they add up.

Glitches can become legitimate strategies

One of the most fascinating parts of speedrunning is the use of glitches.

Games are complicated pieces of software, and players sometimes discover behavior the developers never intended. A particular movement might allow a character to pass through a wall. Performing actions in an unusual sequence might skip a cutscene or confuse the game about which level should load next.

In ordinary play, these would be considered bugs.

In some speedrunning categories, they are tools.

The important distinction is that speedrunning communities establish rules about which techniques are permitted. Some categories allow almost any glitch that can be performed within the game, while “glitchless” categories restrict certain exploits to create a challenge closer to conventional play.

Using a permitted glitch is therefore not necessarily cheating. It can be part of the agreed challenge, and executing difficult glitches consistently may require enormous skill.

Runners practice tiny sections repeatedly

Watching a polished world-record attempt can make speedrunning look almost effortless.

The reality involves enormous amounts of repetition.

Instead of repeatedly playing the entire game, runners often practice individual sections. A difficult movement sequence might be attempted dozens or hundreds of times until it becomes reliable.

This is similar to how a musician practices a difficult section of a song rather than playing the entire piece every time.

Runners also use intermediate timing points called splits. Instead of only seeing their final time, they can compare how quickly they completed individual sections against previous attempts.

If a runner reaches one split three seconds ahead of their personal best, they know the run is going particularly well. If they lose ten seconds later, they can identify exactly where the time disappeared.

This turns improvement into something measurable.

World records can come down to fractions of a second

As a speedrunning community becomes more competitive, the easiest improvements disappear.

Early runners might discover routes that save minutes. Years later, players may be fighting for fractions of a second.

At that point, tiny details become important.

A slightly better movement line, faster menu selection or newly discovered technique can be enough to change the world record.

This is why records can continue falling even in games that are decades old. Players keep studying them, testing ideas and sharing discoveries.

Sometimes one person finds a new strategy that immediately changes how everyone approaches the game.

The record belongs to an individual runner, but the knowledge behind it is often the work of an entire community.

Speedrunning is surprisingly collaborative

Speedrunning looks intensely competitive because everyone is chasing faster times.

Behind the competition, however, communities are often highly collaborative.

Players share routes, explain glitches, create tutorials and analyze one another’s runs. Someone who discovers a faster strategy will often publish it even though competitors can immediately use it against them.

That might seem strange in a competition.

But speedrunning is partly about discovering what is theoretically possible within a game. Improving the collective understanding of the game can be as exciting as holding the record personally.

Communities also maintain leaderboards and establish rules for verifying submitted runs. Record attempts may require video evidence, timing standards and other checks to ensure performances can be compared fairly.

The result is a competition built around shared knowledge.

Why spend hundreds of hours saving seconds?

From the outside, speedrunning can look slightly ridiculous.

Why replay the same game hundreds of times just to finish it 12 seconds faster?

The answer is similar to why people run marathons, solve complicated puzzles or try to improve at an instrument.

Progress feels good.

A game provides a fixed environment where improvement can be measured extremely precisely. You can see exactly how much faster you became and identify exactly where you can improve next.

There is also satisfaction in mastering something deeply.

An ordinary player may understand how a game works. A speedrunner can know how long individual animations take, which walls have unusual collision behavior and exactly how the game responds to particular sequences of inputs.

The game becomes less like a story to complete and more like a system to understand.

Speedruns can make old games feel new again

Some of the most active speedrunning communities are built around games released many years ago.

Once the story and surprises are familiar, speedrunning creates a completely different way to play.

A hallway that once existed simply to connect two areas becomes a movement challenge. An ordinary enemy becomes an obstacle that must be passed in the fastest possible way. A bug that once seemed annoying becomes the key to skipping ten minutes of gameplay.

Speedrunning can therefore extend the life of a game far beyond what its developers originally imagined.

It also creates an unusual kind of preservation. Communities continue documenting, analyzing and playing older games long after their commercial moment has passed.

Speedrunning changes what it means to finish a game

For most players, finishing a game means reaching the ending.

For a speedrunner, reaching the ending can be where the real challenge begins.

The first completed run provides a time. Then comes the question of whether that time can be improved. A minute disappears. Then another 20 seconds. Eventually, improving by half a second can feel like a major achievement.

That is what makes speedrunning compelling.

It transforms a familiar game into a competition against the clock, other players and your own previous performance. Every animation, shortcut and strange piece of game behavior becomes part of the puzzle.

The developers created the rules of the world.

Speedrunners spend years discovering just how far those rules can be pushed.
