Unofficial NeoForge port of Auto Sprint Fix by Amelia. Please report issues here, not to the original author.
If you play with toggle sprint or toggle sneak, the game switches them off when you respawn. With this mod they stay on. On Minecraft 1.21.9 and newer this only happens on servers with instant respawn, older versions do it on every respawn.
Client-side only, works on any server.
