runfast
by kscm1236
RunFast is a Forge and NeoForge mod for Minecraft 1.20.1 and 1.21 that raises sprinting speed, and its author pairs the faster movement with a fan mechanic.
What it does
A player who sprints covers ground much faster than in vanilla, which changes how travel and exploration feel. The author notes that high-speed sprinting can make play fun, and the mod is built around that idea. A configuration file named runfast-common.toml lets server owners set enabled to false to disable the mod entirely.
The mod is installed on both the server and every player's client, since it runs in the client and server environment under the BSD 3-Clause License, which is not open source. Builds cover 1.20.1 and 1.21 for Forge and NeoForge, with 1.0.0 as the latest file for 1.21 on both loaders.
Key features
Faster sprinting
Sprinting moves the player noticeably faster across the ground than the vanilla sprint speed.
Fan mechanic
The mod includes a fan mechanic that the author built alongside the sprint speed change.
Server-side disable option
The runfast-common.toml file exposes an enabled setting, so server owners can turn the mod off entirely.
