In the middle years of the 2010s, when speedrunning was rediscovering classic shooters and puzzle games on modern platforms, a player under the handle CantEven quietly became one of the defining names of the Portal and Portal 2 scene. A musician from Ohio who specialized in Source Engine movement and puzzle routes, he helped push Portal any percent runs under seven minutes, then under six, and led the charge to bring Portal 2 single player runs below one hour.
Across a decade of competition he accumulated a long list of world records and top tier times in Portal, Portal 2, and their many mods and category extensions, while also moderating community leaderboards and bringing those skills onto the stage at Summer Games Done Quick 2019. His work made him one of the most important full game runners in the history of Valve’s puzzle series and one of the clearest examples of how a single specialist can shape the route, culture, and expectations of an entire speedgame.
Origins And Entry Into Source Engine Speedrunning
Publicly available sources place CantEven in Ohio, United States, with his earliest speedrun.com submissions dating back roughly a decade. On his YouTube channel, branded as “Can’t Even,” he describes himself as a player who speedruns Portal and Portal 2 and occasionally uploads recordings of the music he plays, blending performance and optimization in a way that would come to define his presence in the community. His Twitch biography is even more direct, introducing him as a musician and high level speedrunner of many Portal games, which matches the breadth of his leaderboard history.
From the beginning his focus was on Source Engine titles. On Speedrun.com his profile shows long running involvement with Portal, Portal 2, Portal 2 Speedrun Mod, Portal Reloaded, Aperture Tag, Portal Stories: Mel, and even a few experiments in Half-Life 2, along with a handful of smaller games such as Big Brainz: Timez Attack. The pattern is consistent. He gravitated not toward broad multi game variety, but toward one engine and one family of puzzle shooters, and tried to master them in depth.
Portal And The Race To Sub Seven, Then Sub Six
Portal had already been a staple of single segment speedrunning for years by the time CantEven arrived on its leaderboards, but the game’s Out of Bounds and No Out of Bounds categories still had visible room to shrink. Using the same blend of precise bunnyhopping, edge clipping, and save based glitch setups that defined the scene at the time, he patiently worked his way up the rankings and into world record contention.
By 2017, mainstream games press were citing him as the record holder in Portal’s any percent category without going out of bounds with a time of seven minutes twenty seven seconds, alongside 10:58 in the equivalent category by fellow runner BiiWiX. That coverage reflects how central his runs had become for viewers who tuned into Portal speedrunning not through forums, but through general gaming news.
In the following years he shifted more of his full game attention to Out of Bounds routes. A widely circulated video and leaderboard progression show him recording a 5:53 Portal any percent run that at the time stood as a world record, fast enough to be highlighted in articles and blog posts about the fastest speedruns ever recorded. Later improvements by others would push the time even lower, and on his own profile the current personal best listed is 5:49.875 in Out of Bounds, a time that now ranks outside of first but still reflects how far the route moved during his active years.
Along the way, Reddit threads tracked milestones like “Portal beaten in under seven minutes by CantEven,” where he himself appeared in the comments to share a higher quality encode and answer questions about the complex Out of Bounds navigation that defines the modern route. Those exchanges capture him not only as a record holder, but as one of the most visible interpreters of what Portal runs were doing under the surface.
Portal 2 And The First Sub Hour
If Portal established him as a world class full game runner, Portal 2 made him one of the central figures in that game’s entire timing history. His speedrun.com profile documents a long ladder of decreasing single player times in the game’s “Single Player” category, especially in the “No Save Load Abuse” rule set that restricts some of the most extreme glitch setups.
One of his most important achievements came when he recorded a 59 minute 52 second run of Portal 2 single player inbounds, the first time the community had seen the game completed under the one hour mark. A thread on r/speedrun announcing the accomplishment identifies the run as a world record and notes that an in game crash near the end forced him to reload a save. Because Portal 2 full game times are measured by in game time using demo files, the pause in the executable did not affect the final time, but it highlighted how fragile high precision runs could be on real hardware.
From there, he continued to push Portal 2 downward. A streak of videos and leaderboard entries show him at 1:03:25.667, 59:06, and eventually a 57:57 full game run that was presented as a world record at the time and later mirrored on Chinese video site Bilibili. As of the early 2020s his speedrun.com profile lists a 57:27.650 “Single Player No SLA” time that remains among the best recorded runs of that rule set, even as new players have stepped in to contest the top position.
He did not restrict himself only to the inbounds, no save load abuse category. Across several years he also set and refined any percent runs that allowed more aggressive save based tricks. A 38:34 Portal 2 any percent run, tagged as Single Player with save load abuse, was uploaded with the title “World Record” and appears on his profile in the “SLA” listings as a top tier time, with a series of slightly slower orphaned times showing the route’s development.
Mods, Side Games, And Co Operative Play
Although full game Portal and Portal 2 categories are his best known work, the raw leaderboard data reveal a player who constantly explored the boundaries of Source Engine puzzle design. On Portal 2 Speedrun Mod he posted one of the faster Single Player times, under twenty nine minutes in the main category, and experimented with additional challenge categories such as Celeste Mode, where his 51:46.783 time in a hundred percent clear ranks among the leading runs.
He also applied his movement knowledge to community made content. In Portal Stories: Mel he submitted both Inbounds and Out of Bounds Story Mode times, including a 21 minute Out of Bounds clear that reached the podium on its leaderboard and a 33 minute Inbounds story run. In Aperture Tag: The Paint Gun Testing Initiative he recorded an 18:01.600 Inbounds No SLA time, another example of his preference for categories that mirror the strictness of main game rules.
On the lighter side he played with the joke rich Portal Category Extensions boards, where his “Minecraft percent” run in ten minutes one second made use of Out of Bounds techniques and was highlighted on Twitch as a world record when initially performed, even if subsequent improvements by other runners have since pushed it down to ninth place on the leaderboard.
Co operative play was another recurring thread. He teamed with fellow Portal 2 specialist Msushi in several categories, including an All Main Courses co op run in twenty seven minutes fourteen seconds and top tier Marathon percent co op times on the Portal 2 Category Extensions boards. Those performances showed that his skills translated not only to solitary precision, but to the coordination and communication required for two player puzzle routing.
Marathon Presence And Community Work
By the late 2010s CantEven’s Portal 2 runs had matured enough to appear on some of speedrunning’s largest stages. During Games Done Quick’s Summer Games Done Quick 2019 marathon he ran Portal 2 in one hour four minutes twenty nine seconds in a full length showcase segment. For a general audience that might not track leaderboard changes in real time, that performance was often their first exposure to the modern Portal 2 route and to the kind of subtle movement decisions that separated mid tier clears from world class play.
Outside of his own runs he took on formal community responsibility. Speedrun.com lists him as a moderator for Aperture Tag and for the bridge building spinoff Bridge Constructor Portal, indicating that he helped verify submissions and maintain rules for those games. His frequent visits to the Portal 2 leaderboards, challenge mode sites, and related forums suggest the kind of long term, day to day involvement that rarely appears in highlight videos but is essential to a stable leaderboard ecosystem.
His social presence reflects the same focused identity. On X (formerly Twitter) he describes himself as a speedrunner of various Source Engine games and directs followers toward his Twitch channel. His YouTube playlists are organized around Portal Out of Bounds speedruns, Portal 2 world record runs, and challenge mode segments, making the channel a rough archive of his own progression through the series.
Style, Musicianship, And Approach
While raw times define a record, style is what makes a particular runner memorable. In commentary, clips, and marathon appearances, CantEven often approached Portal and Portal 2 runs with a musician’s sense of rhythm. The games’ long chains of bunnyhops, wall strafes, and portal placements resemble difficult musical passages, and his best runs often feel less like frantic improvisation and more like a practiced piece played at the edge of what is physically possible.
The Reddit discussion around his first sub hour Portal 2 run highlights how he navigated not only mechanical skill but also the quirks of the tools used to measure time. When his game crashed near the end of that attempt, he relied on an intimate understanding of how Portal 2’s in game timer works and how demo files pause when the executable is not running, allowing him to salvage the run without compromising its legitimacy. That mix of technical literacy and performance under pressure is characteristic of high level Source Engine runners, and he is one of the clearest examples.
Legacy In The Portal And Source Engine Community
Measured over ten years of activity, the breadth of CantEven’s work is striking. His profile records more than one hundred fifty full game runs across at least eight games, the majority of them in the Portal family or closely related Source Engine titles. He pushed Portal’s Out of Bounds any percent route into the mid five minute range, held recognized world records in both Portal and Portal 2, broke the one hour barrier for Portal 2 single player, and helped develop and document routes across official sequels, community mods, and joke categories.
Even after other runners surpassed his times, mainstream articles about the fastest speedruns ever recorded, along with long form blog posts about Portal and its sequels, continued to cite his name and his best known records, preserving him as one of the key historical figures attached to Valve’s puzzle series. For the purposes of a Speedrun Legacy Profile, that is the heart of his story.
He took a narrow slice of games, mastered them across multiple categories and rule sets, mentored and moderated within their communities, and left behind a body of work that still shapes how runners talk about Portal and Portal 2 today.
