Player Speed bug

is it a way to make the third person character move faster at frame 0 or 1?
when I set the speed to 24000 or 9999999999999999, the character need to walk like 5-10 sec before the he start to run.
How can I set min speed, or set it on the character will run when I press the walk button? I did try to set the max speed, but the character can’t get to the max speed as fast as I need him to.
Please help me, or tell me if this is a bug. Last thin I did scale the character to fit to the terrain.

You can change the acceleration so they reach the max speed faster
