But at the beginning of the game Hugh can be battle during this mode so does that mean after I defeat the champion I start the entire game over again.

Someone else is able to turn on Challenge Mode for you if they have it.

No, you unlock a "key" which unlocks Challenge Mode when you beat the champion. Then, you can use the Unova Link in the menu to connect with other BW2 games and transfer it.
