In Rec Room, speedruns are play-throughs of one of the Quests with the intention of completing it in the shortest amount of time possible. Players attempt speedruns mainly to challenge themselves and to entertain as well as compete with others.
Players performing speedruns call themselves "speedrunners." In the past, they would add SR to their display name in order to distinguish themselves from casual players and to signal/warn others that they will likely progress through quests quickly and recklessly, normally without regard to the final score. The trend of adding the SR title has since dwindled, but the spirit of speedrunning continues, especially with the addition of new quests and movement modes.
Details relevant to a speedrun are the name of the Quest that is being run, the version (as quests are often changed in updates of Rec Room), the number of players in the team, and the achieved rank.

Additional Details & Terminology[]
Rushing[]
Rushing is when one or more members of a speedrunning team move or "rush" ahead to a certain location or work to accomplish a required task in order to spawn as many waves as possible, with the intent of clearing each level/act as quickly as possible. The exact mechanic behind rushing depends on the quest, as certain quests simply require a player to be at a certain location while others require all or a set number of enemies to be eliminated in the area.
Glitching[]
Glitching is when a player finds and exploits a flaw in order to achieve something that was not originally intended by the game designers. Most Rec Room speedrunners use glitches to skip entire parts of levels (for example, the skip in Act 3 of Golden Trophy). These glitches are only allowed in Any% speedruns. There is another category called Glitchless, where these glitches are not allowed.
There is one notable exception in Glitchless speedruns is the double shot. This particular glitch allows players who use a bow to fire two arrows with a single draw, essentially doubling their rate of fire. It can be utilized in the Quest for the Golden Trophy and The Curse of the Crimson Cauldron. This was first used in an official speedrun in December of 2017. There has been some controversy to its use, but it has been utilized in nearly every speedrun since 2018 and has made it possible to achieve much lower times than before. It has also been kept as an official mechanism for quests since the addition of the game mode Rec Royale, where the double shot feature is disabled.
Exploits[]
The use of exploits varies from glitching in that exploits improve a speedrun time but do not break the game's originally intended mechanisms. These are encouraged and are often necessary in speedruns. An example of a common exploit is the turning of the goblin king in the last Act of Quest for the Golden Trophy where speedrunners will have one player, generally the first person to spawn into the room, draw the attention of the goblin king to the side while the remaining players attack from the opposite side. This allows players to rapidly eliminate the boss without having to deal with the waves of enemies that spawn as the goblin king's health is depleted.
Routing[]
The routes that players follow during a speedrun. For example, in a duo speedrun of Quest for the Golden Trophy, in Act 2, one player will stay back and take enemies near the entrance, and the other will be ahead and will take enemies near the exit. Speedrunners try to use the most optimal routes which are the ones that are fastest.
Submitting[]
Records are usually communicated by posting screenshots of the final scoreboard or a video on the Rec Room subreddit www.reddit.com/r/RecRoom or on Rec Room's discord. Attempts can also be submitted to www.speedrun.com/Rec_Room.
