CharacterContoller Speed Problem

Hi All,

im using charactercontroller for movement character system and using rightclick ground method to move as walk/run
but i have problem about speed.
while im click in ground/terrain near myChar, then myChar will walk/run normally with normal speed.
but
while im click far from myChar, movement start with high Speed and then Lerp to Slow based distance click posistion between myChar.

i need to myChar do movement as normal speed or constant speed.

please HELP me..what wrong with cc?
