Probably one of the more difficult achievements in the game, but not difficult enough to prevent you from completing the game.
For this one you will want to win the race in Olympic Mode by avoiding the obstacles and bashing your opponent into them so that they take more damage!
The bumpers can be used to push their chariot into the obstacles depending what side they are on (press
if they are to your left to push them towards the left side of the screen into an obstacle and
if they are to your right). He will try to bash you as well so use
to protect your self.
