Sprint jump nerf
by GalatynF
Sprint jump nerf removes the speed boost that a sprinting jump normally gives the player on Fabric for 1.21.1.
What it does
Sprint jump nerf takes away the forward speed boost a player gets from jumping while sprinting. Version 1.1 changes the behavior so that the traditional sprint jump still works once every 3 seconds, which keeps long gap jumps from feeling too restrictive. Every player and the server need a copy of the mod. Latest Fabric file: 1.1 for 1.21.1, released 2026-05-10, under the MIT License and open source.
Key features
Boost removal
Sprint jumps no longer add the flat forward boost that normally applies while the player is sprinting and jumping.
Timed traditional jump
From version 1.1 on, a traditional sprint jump is still allowed once every 3 seconds, so gaps stay reachable.
Normal running
Players who prefer ordinary movement keep their regular running speed without the extra jump boost.

What the author says
Removes the boost you get from sprint-jumping. I deleted a line of code that added a flat boost to the player if they're sprinting while jumping. Now enjoy running normally like a sane person! From version 1.1 onwards you can still perform a traditional sprint jump once every 3 seconds, to make jumping gaps easier.
