This is how to gain permanent sprint without losing stamina. You need to have double jump and a melee weapon equipped.
Run forward while holding down sprint.
Jump and let go of all keys.
While in the air Tap sprint and jump (requires double jump).
When you land you will notice you are doing a hovering/falling animation.
Do this a few times until you master it.
Now that you have mastered that part the next step is to just hold down the forward key when you land. To know you have done it correctly you will be moving in the hovering/falling animation. This part might take some time to get down. I find that holding down forward once I hear my feet land seems to work the best.
Now you will be running forward at full sprint speed without losing stamina just by holding down forward. To everyone else you will be floating around their screen really fast. So you will want to hide this animation by doing a quick whirlwind. That will put your feet on the ground and it wont break permanent sprint.
Just keep in mind you can only melee and run forward or else it will break and you will have to do it again. Also you can do this backward, but that will get you reported fast. Enjoy
