Convert the player.lsb in the mod into a player.lsx.

Open it with Notepad++ (it'll be unreadable with plain Notepad)

Replace Runspeed "6" with 8 or whatever for the player and the companions and henchmen. You could also increase walk speed if you want (though I'd probably still keep that below 4)

Convert the Player.lsx back into Player.lsb (just select player.lsx as the one to convert, locate the folder where you found it in the mod, and change the save name to Player.lsb and hit convert).

You don't need the Player.lsf (works for me with just the .lsb anyhow) or to do any hex editing. Probably need just the lsf or just the lsb, not both. I couldn't even convert the lsf for some reason, so use the lsb.
