Welcome! This is an extensive guide to speedrunning Portal! Here you'll find everything you need on your speedrunning journey, from the basics of setting up the game, to the most advanced strategies a runner can learn.
If you're new to this, read through the Setup Guide.
Otherwise, jump ahead to the tutorials:
Glitchless - Inbounds No SLA - Inbounds - Out of Bounds
The most important step for setup is installing the right version of the game for speedrunning. If you want to run glitchless, the Steam version of the game is completely fine, although you'll have to manually install any additional software or resources. If you're running any other category, you'll want to use Source Unpack.
Source unpack is a package including a stand-alone copy of build 5135, an older version of the game that makes certain glitches significantly easier. Source unpack comes with everything you need pre-installed, so it's as simple as downloading the package, unzipping it, and running it. In order to use Source Unpack, you must own Portal on Steam, and Steam must be running.
You can download Source Unpack from here. Pick the server (Europe/US/Asia) that is closest to you.
Livesplit is the software we use to time runs as they're performed. It's the timer you see in the corner of runs.
Livesplit isn't a Portal-specific piece of software, so it's not included with Source Unpack. You'll need to download the latest version of livesplit from the livesplit website. Once you have it, you'll also need a splits file for Portal, which you can get here.
Open the splits file in livesplit, and you should have a list of chambers from 00/01 through to e02, though they aren't all shown at once by default.
Right click and press edit splits. This will bring up a menu where you can configure a few things about your splits file.
Towards the top, there's a "Run Category" text box. Change this to match the category you plan on running. If you're planning on running multiple categories, you'll need to have multiple splits files.
While you're on this screen, you can confirm you have Sourcesplit. Sourcesplit is an auto-splitter, meaning it will automatically start and stop the timer, as well as removing any load times from your run, to keep it fair between different computers. It should install itself automatically, but it's good to check.
Towards the top of the edit splits window, livesplit should say "Game Time and Auto Splitting are available. (By Fatalis and 2838)". If the button beside that says "Deactivate", the auto-splitter is loaded and ready! If it says "Activate", click it to activate auto-splitting. There's a bunch of settings you can play around with in sourcesplit, but the defaults are fine for running the main categories. To make sure the auto-splitter is working, open Portal and start a new game. The timer should start ticking as soon as your crosshair appears.
Finally, close out of the edit splits menu and right click on livesplit, hover over the "Compare Against" option, and ensure that "Game Time" is selected at the bottom. Sourcesplit should set this automatically, but it's a good idea to double check.
We do this because livesplit tracks two types of time, your time without loads (game time) and your time with loads (real time). For the leaderboard, we only care about game time (or "load removed time" on speedrun.com) but you can additionally include the real time (called "real time attack" on speedrun.com).
And that's all for setting up livesplit! Right click and save your splits!
If you installed Source Unpack, skip ahead to the Binds and Configuration section!
(Reminder: you can skip this section if you are using source unpack)
Demos are a built-in feature of Portal and other Source engine games. They're effectively "replay" files that you can record and play back from within the game. Demos are the gold standard for recording speedruns, as they give the speedrun.com verifiers the ability to inspect your run to a much greater extent than with a video recording.
The default demo recording commands don't let us use quicksaves, and also just dump all the recorded demos in the install folder, so instead we use a custom plugin that manages demo recording.
You'll need to install this plugin. If you're on the steam version of the game, download the speedrun_demorecord-2013.dll file. If you're on an older version for whatever reason then you'll instead want the speedrun_demorecord-2007.dll file. The 2006 version is only for recording demos in old versions of Half-Life 2.
Once this is downloaded, navigate to your Portal install folder. On steam, this can be done by right-clicking on Portal in the games library, clicking on "Properties", going to the "Installed Files" tab and clicking on the "Browse..." button. I'd recommend pinning this folder to quick access in File Explorer, so you can get back to it later.
You'll want to place the dll file you downloaded in the Portal/portal/ folder. Note that there are two levels of Portal folders here. The dll needs to be placed in the innermost one, the same folder that contains gameinfo.txt.
Note for 3420 And Older Builds
On older builds of Portal, plugins must be placed in the Portal/bin/ folder rather than the Portal/portal/ folder.
Once you've done that, you can load the plugin in-game via the developer console, but doing that every time would be a pain. Instead, we're going to setup an autoexec that will load it for us.
Open the Portal/portal/cfg/ folder. There'll be a number of .cfg files here. If there's already an autoexec.cfg file, great! If not, you'll need to create a new text document and name it autoexec.cfg. Make sure that filename extensions are enabled, or Windows will sneakily give your file the name autoexec.cfg.txt. If the existing files don't show .cfg, do a web search on how to display file extensions in Windows explorer for your respective version of Windows.
Edit the autoexec.cfg file. Each line in this file is a console command that will be executed every time the game starts. This is where we're going to load our plugin.
Add a line with plugin_load speedrun_demorecord-20xx, adjusting the 20xx to match the version of the plugin you downloaded.
I also recommend setting up a custom demo folder here, as otherwise the plugin will fill your portal folder with demos.
Add the line speedrun_dir ./demos/. This will instead put all the created demo folders in Portal/portal/demos/, which will be much neater.
Now, every time you open the game, the plugin will be loaded and configured correctly.
(Reminder: you can skip this section if you are using source unpack)
The start of Portal involves a minute-long cutscene in which the player is free to mess around, but can't do anything to speed it up. In the interest of maintaining their sanity, Portal runners typically start their runs by loading a save towards the end of this cutscene. Specifically, they load a save that starts exactly 53.025 seconds into the run, and the same amount of time is added on by the auto-splitter. This save can be downloaded from here.
This is the only save that is permitted, making your own is not allowed.
You need to extract the .sav file from the .7z archive. For this, I recommend 7zip.
To install it, place it in the Portal/portal/save folder. On older versions, save might instead be SAVE, but the process is no different.
How to actually use the save is covered in the Performing a Run section.
While it's possible to complete speedruns with the default binds, there's a number of very helpful additional binds that will be listed here.
These binds are provided as console commands. To run console commands from in-game, first ensure the console is enabled by going to Settings>Keyboard>Advanced and checking the "Enable developer console" box. Now, you should be able to use the backtick/tilde key (`/~), next to 1 on most keyboards, to open the console. If you can't find this key, or just don't have it, you can bind it to something else in the keyboard settings. One of the function keys is a suitable choice.
Once you have the console, you can use the commands below.
<key> represents the key you want to bind the function to. Replace it with the key you want (i.e. bind <key> becomes bind q or bind ctrl).
Any instances of A|B mean that you can put A or B. If you want both, make two separate binds.
bind mwheelup +jump&bind mwheeldown +jump- Binds the scroll wheel (up and down respectively) to a jump input.
- Required for performing optimal movement in all categories.
bind <key> "save quick"&bind <key> "load quick"- Sets your quicksave and quickload keys. Can also be done through the menu.
bind <key> "load quick01"- Loads the second most recent quicksave. Useful for when you save at a bad time.
bind <key> "save glitch; load glitch"- Make a save and load it at the same time. Very important for Inbounds and Out of Bounds speedruns.
- Note: "glitch" is just the name of the save. You could use any name.
bind <key> "load glitch"- Reloads the save in the above command. Useful in the event of a mistake.
bind <key> toggle_duck- A key that toggles your duck state, as opposed to normally needing to hold it down. Useful for certain glitches in Inbounds and Inbounds No SLA, as well as for movement in all categories except Glitchless.
bind <key> sv_player_funnel_into_portals 0|1- Using 1 will enable portal-funneling, 0 will disable it. Having a bind for both is recommended.
There's a few other useful commands you may want, but aren't worth binding. Instead, run these via the console or append these to the end of your autoexec.cfg file (Refer to the Adding to Autoexec section if you didn't install the demo recorder manually.).
cl_showpos 0|1- Shows your position and angle in the top right corner.cl_showfps 0|1- Shows your frames per second.net_graph 0|1- Shows some data about the game, including frames per second
Now that you've setup all your binds and know how to use the developer console, you can perform your first run.
There's a minute long cutscene at the start of Portal, but we're going to skip over that by loading the vault save.
Open the developer console and run speedrun_save vault. This will tell the demo recorder that you want to start your run by loading that save. You may wish to add this to your autoexec.cfg.
Now, run speedrun_start to load the save and start your run. If you want, you can add this as a bind. Livesplit should pick up on the fact that you loaded the vault save and automatically start at 53 seconds. From here, you can perform your first run. Feel free to just run through the game once with the timer running, to get a feel for it, but it's best to go through all the beginner tutorials for your chosen category and learn some strats before submitting a run to the leaderboards. It's also a good idea to read over the Submitting a Run section so you know what you have to do during the run in order for it to be accepted.
Once you've defeated Glados (and the neurotoxin starts circling up), you need to run speedrun_stop in the console in order to lock in the demos for the run. It is very important that you don't forget this step, as you can easily have your demos corrupted if you don't. The best time to do this is straight after Glados dies. You can unpause and watch the rest of the ending cutscene if you want, but it's best to stop the demos straight away.
In order for your run to be accepted, it must follow the rules of the category you're submitting to. You can see the rules for a given category by clicking the "Show Rules" button on the speedrun.com leaderboard.
All Portal runs require proof in the form of either demos, or a live video recording. For a live recording to be valid, it has to include game audio and show the livesplit timer the whole time. The best software for recording runs is OBS.
Demos will always be valid, so long as you did not pause. Pauses are timed in Portal, and demos don't record how long the player paused for. For this reason, if you pause during your run for any reason, you need to provide a live recording.
To submit with video, upload it to a video-sharing service such as youtube. Whatever service you use must provide permanent hosting. Add a publicly accessible link in the video field when submitting.
To submit with demos, upload them to a file-sharing service such as google drive. Whatever service you use must provide permanent hosting. Add a publicly accessible link in the description when submitting.
With that, you now know everything you need in order to speedrun Portal. All that's left now is to learn the strats and practice, practice, practice.

- A strat that can be repeated from chambers 13 through 18, beating them all in roughly the same way.
- Uses VWW or FSG to save a small amount of time per chamber, totalling around 5-7 seconds over the entire run. Is a lot more difficult than UE1 and saves very little.

- Uses an AAG to teleport into Glados' chamber, bringing a turret with you
- A somewhat precise save glitch that has the potential of saving 2-3 seconds over the AAG route. VWW can be tricky because of the long loading times in e02. Builds with free oob can do the crouch into the level transition, while in builds without you will need to portal yourself over to the same area.
